An anonymous reader writes: *There's often debate amongst modern programmers about how much math a professional developer should know, and to what extent programming is math. Learning to program is often viewed as being on a spectrum between learning math and learning spoken/written languages. But in a new article, Jeremy Kun argues that the spectrum should be formulated another way: Human language -> Mathematics -> Programming. "Having studied all three subjects, I'd argue that mathematics falls between language and programming on the hierarchy of rigor. ... [T]he hierarchy of abstraction is the exact reverse, with programming being the most concrete and language being the most abstract. Perhaps this is why people consider mathematics a bridge between human language and programming. Because it allows you to express more formal ideas in a more concrete language, without making you worry about such specific hardware details like whether your integers are capped at 32 bits or 64. Indeed, if you think that the core of programming is expressing abstract ideas in a concrete language, then this makes a lot of sense. This is precisely why learning mathematics is 'better' at helping you learn the kind of abstract thinking you want for programming than language. Because mathematics is closer to programming on the hierarchy. It helps even more that mathematics and programming readily share topics."*

From the ambiguity within your comment (what language, natural or programming?; Is the fact that you can pickup this that or the other in 8 hours

If you have a grade 8 math level, then you're probably comparing yourself to people in grade 8. Most people in grade 8 simply memorize facts and spew them back on a poorly-designed test without understanding anything, because that's what the school system is about. This means you're very likely claiming that you're absolutely abysmal when it comes to understanding math.

A "programmer" can be someone who spends two days putting together a complex Excel macro (poorly), or someone who designs an information systems architecture for a significant enterprise. These are VERY different activities.

On top of that, I'll say that approximately 85% of people doing programming aren't really competent. Compare how often software crashes vs how often cars fail in such a way that they crash themselves. So you have to specify, are you talking about MOST programming, or competent programming? Most programming isn't done competently.

Well-designed and larger software projects require a thorough understanding of a large set of rules, both knowing what the rules are, and understanding WHY the rules are as they are, and when to apply which rules in order to move forward. In that sense, it's very much like math. Also like math, one wrong decision can lead you down a path of futility, from whence reversing course is time-consuming.

Even if one is going to follow the idea that it is not math itself one should learn and more the abstract reasoning one picks up while learning match, even that is questionable since the amount of abstract thought that is useful varies from task to task and environment to environment.

Math is a language. Just because you can frame things in that language doesn't mean that that language is necessary. Recipes are often in English. English is sequencing (words are a serial stream after all). That doesn't mean English is necessary for programming (there seem to many competent non-english speaking programmers as far as I can tell).

The problem with all the articles like this is that they're either written by people who did take math or didn't, and in either case both believe their side is right. The article is clearly written by someone who took a lot of math so, surprise, he thinks math is good for programmers. But I took nothing past Calculus (and have never professionally used even Trigonometry), and I'm a successful programmer, so I think math is unecessary.

Until someone actually does a study on this, it's all gonna come down to "the way I did it was better" ... and that's just noise.

On the other hand, if you work with RF you will most likely need a lot of math. If you work with high level optimization algorithms you will need Abstract Algebra. If you work with Geolocation you will need a fair amount of high level Geometry, specially Non Euclidean ones.

So in the end the answer is: Higher Math is not necessary in all fields of programming but it is certainly very necessary in many.

Formal logic is a branch of mathematics.Yes, I know, but very few people except mathematicians think of it that way. Most people consider it to be an entirely different study so I phrased it that way to emphasize that much of computer programming has nothing to do with what the average person thinks of as math.

In the end, I've always concluded the same, every year this topic comes up (it is just about annual here). I don't want you to know calculus because you'll actually use calculus on the job (though I have an O(N) vs O(log(N)) question on my interviews that you'd better be able to answer).

I want you to know/pass calculus because by the time you've worked that hard at that level of proofs, you've mastered *variable control*. In each level of math, you don't get out of the class having mastered it. You get out of the class having mastered the year that came before it. When you can pass calculus, you have *mastered* functions and analytic geometry (I hire for UI work). Passing those two the year before showed you mastered variable manipulation and proofs in Algebra 2 before it.

So no, you don't *need* calculus on the job, but you need everything below it, and the best proof that you've *mastered* them (not just taken them, but mastered them) is that you've passed a calculus class.

This is silly. You don't need incidental math to learn skills essential to programming. College education wastes countless hours teaching academic stuff that a great majority of programmers will not use on the job, while neglecting critical skills that could be immediately useful in a large .

If you want to teach "variable control", whatever you mean by that, then teach that in respect to programming, not high-level math that will only be used by a tiny percentage.

Yes, I've heard the "well rounded" person argument. I can even accommodate it, to a certain extent, but it would stop at being exposed to ideas versus having to become competent at doing calculus problems in order to pass a course. I personally am not interested in doing calculus and haven't made use of it in over 20 years of programming.

Whether or not you believe that the role of universities *should* be vocational training, the curriculum and organization of institutions of higher education---particularly research universities---is still geared toward that Enlightenment ideal of academia.

Colleges are basically turning into poor imitations of vocational schools. The same is true for some universities. You get the worst of both worlds.

Calculus is perhaps not the best measure however. Depending on where you go in the programming field calculus is likely less useful than some decent depth of knowledge in graph theory, abstract algebra, category theory, or combinatorics and optimization. I imagine a number of people would chime in with statistics, but to do statistics right you need calculus (which is an example of one of the directions where calculus can be useful for programming).

Of course the reality is that you don't

needany of those subjects. Those subjects can, however, be very useful to you as a programmer. So yes you can certainly be a programmer, and even a very successful and productive one without any knowledge of calculus, or graph theory say. On the other hand, there may well be times when graph theory, or calculus, or statistics could prove very useful. what it comes down to is whether you are inclined to think that way -- and if so it can be a benefit; if not it won't be the way you think about the problem anyway.## Re: Your Results Will Vary (1)

I think part of the problem is that "programming" is itself so diverse.

The other part of the problem is that math is so diverse. There's calculus and engineering math with all kinds of techniques for solving this or that PDE; there's set theoretic foundations; there's graph theory and design theory and combinatorics and a slew of other discrete math topics; there's topology and metric spaces and various abstractions for continuity; there's linear algebra and all the finer points of matrices and matrix decompositions and tensors and on into Hilbert spaces and other infinite dimensional things; there's category theory and stacks and topos theory and other esoterica of abstraction. On and on, and all very different and I can't even pretend to have anything but cursory knowledge of most of them ... and I have a Ph.D. in math and work for a research institute trying to stay abreast of a decent range of topics. The people who actually study these topics in depth are all called "mathematicians", but if you're an algebraic geometer then sure, you're probably familiar with category theory and homological algebra; if you do design theory and graph theory then those seem like the most useful subject available.

I guess it depends, I have used math twice n my professional career - once to use trigonometry to show the distance between 2 points (Pythagoras) and once with a complex equation that was reduced to a simpler one.

Now, if I was a cryptograpic engineer, I think I might use math more often :)

But, as I tend to be more of a LoB engineer, math is not something used very often at all. If at all. I refer to the aforementioned pythagorean equation for the distance between 2 points using a triangle.... the business people I was working with considered me a genius for knowing that kind of thing even though it was something remembered from my O level days (yes, I'm old, maybe they don't teach it any more)

For LOB applications often you are making specific domain languages so you should know your grammars, also understand complexity in computer science terms is VERY useful.

The problem is, you've actually used maths every day in your career, you just haven't realised it. When you are programming, you are by definition doing maths - programming is a branch of discrete applied maths.

Actually knowing the theory of discrete applied maths obviously makes you better at doing discrete applied maths.

My first idea was to say: "I second that" but then I remembered that I'm not a native english speaker and that I indeed did some math (Trigonometry) heavy programming.

However: my university focused in the computer science education math in the first two years (University of Karlsruhe, german, now called KIT). Hence the most drop outs happened in that period.

My school math education was very good, geometry and Trigonometry was never a problem, after all it is simple math defined by Euclid and Thales 3 thousand years ago.

Nevertheless I nearly either failed or lost interest in my CS studies because of the mandatory math classes. (I'm not bad at math, but I do not like studying it for no purpose or into arcane depths)

I'm a professional software developer since 40years, predating my university studies 10years with programming games and financial applications on Apple ][ s

The math 'they' demanded from me I never needed the last 20 years, and they are still not able to teach:

o programming

o some simple UML modelling

o anything about architecture

o even software engineering is on a very low level

Sorry, the idea that math helps in programming is completely idiotic.

The problem of programming is mapping human problems to computer solutions.

The key to that is requirements engineering, finding an architecture and conducting the actual doing (programming).

In the real hard core programming there is no math at all involved. Well, at some point it comes, so having an open eye helps, scalability e.g is a thing, but it is tackled with architecture, not with math. Math only helps to foresee and address it, not to solve it.

## Re:Your Results Will Vary (2)

## s.petry (762400) | about 4 months ago | (#47486719)

The reason math helps a whole lot in programming is that it teaches essential critical thinking skills. Some people are good at critical thinking skills without taking math. The _majority_ ,however, require some type of education to help mold their methods of thinking. Many, even with a whole lot of training do poorly with critical thinking skills.

Claiming that you have never used math in programming simply demonstrates that you are not programming for scientific purposes (writing a GUI for a CAD program is not the same as writing the underlying math structures). That's fine, and most surely is not intended as an insult. As with above, you are not everyone, and math has many benefits.

I say this as a person who has a degree in Math, and took everything possible in College for math (hated statistical math, but diff-eq was great). I don't sit and run differential equations all day, but do very well helping Engineers and Scientists that _do_ run heavy mathematical models.

I find that most people trying to argue against math generally are doing so by asserting that if a certain math is not put to practice in the software that a person is developing that that math is unnecessary. It also seems to be commonly asserted that persons with a strong mathematical background are just being pretentious.

I believe that the anti-math crowd is missing the point. For a software developer it isn't the skill of solving calculus problems, but the skills required to solve calculus problems. What I mean by this is that in order to work to a solution for a given mathematical problem you are exercising many other skills. Skills such as logic, abstraction, visualization, etc. are very much employed in software development. You go to the gym not because you have aspirations of mastering a bench press, but because you aspire for a stronger, healthier body. Mathematics are an example of exercise equipment for a software developer.

## HiThere (15173) | about 4 months ago | (#47486923)

My feeling is that anything beyond algebra is unnecessary for programmers (in general) EXCEPT logic. I think every programmer should have two or three semesters, or even years, of logic. Programming languages just don't cover quite the same area, and usually skimp badly on logic. (I will agree, however, that theoretically the logic could be taught within the context of programming, except for a tiny bit that should deal with reasoning in unbounded contexts, i.e., infinitesimals, infinities, omega-completeness, etc. and that could be covered within a single quarter. It's just that programming classes don't bother to teach logic, because they assume that you got it elsewhere.)

While the ideas of mathematics are (usually) precise, the language is fuzzy, informal and requires a lot of context. Everyone who ever has compared a fully formal proof and one done in the typical style mathematicians use can immediately see that. On the programming side, there is no room for fuzzyness. Or rather, whenever it is found, it typically is a bug and often a security vulnerability.

the language is fuzzy, informal and requires a lot of context.

Programming and mathematics have the issue of context in common: the interpretation of both are much more unambiguous and context free than most natural languages. Were the languages of mathematics more context dependent, there couldn't be as much international scientific collaboration and progress.

Another similarity between the two is the effort of complete modelling: mathematics models objects with specific properties and their relationships and properties of those relationships as completely and consistently as possible, so does programming where the objects are data and processes specifically. The objects and processes are in turn models of information and behaviour of the world to be described by the mathematician or programmer.

Expressions of natural language have often the same goal (a novel), but may also leave purposeful ambiguities (humor) and contain constructions which have purposes and meanings outside of the language semantics (poetry).

Actually natural languages cannot be described mathematically.

Having also taken the time to read Mei's post, it would appear that (a) Kun is not misrepresenting her point of view, and (b) she is sincere in her opinion.

## Never had to use any college math on the job (1)

## mrflash818 (226638) | about 4 months ago | (#47486517)

Knowing the concepts may have helped for some work I have done, but, I have never used any advanced math for paid programming.

Five years as a J2EE developer: zero use of any advanced math for work projects.

Numerical methods (using Fortran) was just in school.

Calculus, linear algebra, and such: just in school.

Big-O notation, to pick algorithms and STL objects, sure, but probably doesn't count as 'math' for this article.

Since only a fraction of Computer Science graduates will work at a science shop (JPL, etc), I think some of the math requirements are a bit unfair. Perhaps I am just a low-range "Forrest Gump" programmer, but my personal experience was the actual math was burdensome to do to work towards a Computer Science degree.

So you routinely write a = b / c * d instead of a = b * d / c because you're ignoring precision issues do you?

## Forget math, programming is like organic chemsitry (2)

## alphazulu0 (3675815) | about 4 months ago | (#47486573)

As long as we're making gross generalizations...

A big part of organic chemistry in college is "synthesis" problems where you are presented with a molecule and you're supposed to outline the steps (chemical reactions) required to turn it into a different molecule. I find that this closely mirrors programming where we're manipulating data instead of chemicals. We all have access to the same tools and there's more than one pathway that will work, but we're trying to find the most elegant / efficient solution to get from A to B.

Most of the students in my OChem class were premeds and many of them struggled with the synthesis problems. A lot of the premed curriculum involves memorizing and regurgitating huge amounts of information, with less emphasis on problem-solving. I always thought the ones that were good at the synthesis problems should switch gears and become programmers.

It was all the shortcuts, left out "intuitively obvious" steps, and sloppy use of variable names and symbols that drove me up the wall trying to learn advanced math from (imho crappy) math profs.

Let me tell you about the lecture with no less than three different Epsilons (a rounded one, a less rounded one, and something in between) used in the exposition of the proofs. That and my slight myopia kind of did me in in that class (or would have if I hadn't cribbed notes from my neighbour.)

Or, when, as a math prof, giving an example of applied math used for something like physics, why don't we just pick completely random variable names, instead, of, say, using m for mass consistently, v for velocity, etc.

I understand some kind of need to force people to think only of the form and not imbue terms with more semantics that aren't necessarily there in a particular mathematical formal system, but holy cow, could you be more obscure? Why yes I could. I will use 's' for mass on this page, and r' for mass on this next page, just to see if you are paying attention. !!!

Indeed. A for loop is infinitely more intuitive than a big sigma symbol and so approachable that 8 year old kids can make games in BASIC. All of mathematics needs to be reformulated into a grammar that's understandable by machines. Why? Because then ordinary humans will also have a chance at understanding it sans literally retarding lecturers -- Who won't even talk to a 9 year old that's starting to develop his 3D software rasterizer...

You see, if we reformulate math as programming then we won't need the professors. It's a war against the entrenched elitists vs the common man over access to information.

The greatest of all mathematicians, Carl Friedrich Gauss, stated, "I mean the word proof not in the sense of the lawyers, who set two half proofs equal to a whole one, but in the sense of a mathematician, where half proof = 0, and it is demanded for proof that every doubt becomes impossible."

Not much room for ambiguity in that.

It just gives you the tools to better comprehend what's going on under the hood, so you have more information to make the right choices in how to implement something.

What maths is is a mindset where practical problem solving skills can be learned. This can happen at a "basic" maths level and at a higher level.

Clearly the submitter and the blurb have it wrong. It should be: human-language => programming => mathematics. Why? Well its obvious. The United Statian government allows patents on programs, and doesn't allow patents on mathematics. Clearly it can't be human-language => mathematics => programming, otherwise all of the patents on computer software would be worse than having patents on mathematics (which is illegal). Now it can be argued that (all) computer software can be reduced down to mathematics, so then it reads: human-language => mathematics == programming, but again, this flies in the face of US patent law. (Although the premise for the last assertion has been proven mathematically). Unfortunately a mathematical proof does not hold up in a court of law (at least not in the United States).

## I programmed Asteroids in Assembly when I was 12 (2)

Interestingly enough, I sucked at "school math" and flunked math entirely. Imagine the expression on my math teacher when he saw me coding in assembly at the new computer-park back in the 80s, when he barely could understand basic.

Since, I've made numerous demos in the DemoScene with Amiga, and later on coding robotics AI with MCUs (as a hobby, nonetheless).

So no, you can absolutely learn to code quite decent software and hardware without deep math skills, but it helps if you want to do real advanced stuff like coding your own Render-Engine (but then again, how many are they?) My advice - learn whatever you need to achieve what you want.

## conflating code DOING math with code BEING math (1)

## flipk (1187739) | about 4 months ago | (#47487147)

A lot of commenters here seem to be (incorrectly) conflating code which DOES math with code BEING math. Yes there's a lot of products that need high math (i.e. simulations) but there's also a lot of products that are successful when they do extremely complex data movement and organization but very little mathematical transformations.

If programming was so close to math, wouldn't people who are really good at math write the best code? Maybe that's a straw man statement, but in my experience, the people who are really REALLY good at math (e.g. the radio frequency signals processing guys) happen to write the worst code I've ever seen. I've spent much of my career taking prototypes written by DSP engineers and making them go 10 to 100 times faster and use a tenth as much memory. That's not belittling their skills! They did something absolutely amazing that I cannot do, coming up with the steps and crazy weird math required to process signals. (And often, even though I make their code go way faster, I still don't really understand the math behind it when I'm done.) Their code just happens to not take proper advantage of the hardware or other resources. They do the equations so it *functions*, but they don't know how to make it *fast*.

The real skill comes from being able to picture the structure of the data in your mind as complex interconnecting shapes and mentally animate the movement and transformation of data in as few steps as possible without redundancy or useless or redundant transformations; and in many cases, being able to picture multiple workers doing their work in parallel is a plus. I'm not saying every great programmer uses their visual cortex, just that they can keep track of a lot of moving pieces in their mind.

This isn't math. This is more like a visual/spatial skill, like a mechanical engineer designing a complex machine with a lot of moving parts that have to fit together perfectly and move through each other's space in perfect timing. I think it's a different part of the brain from either math OR language.

I have to agree with Kun that complexity analysis (big-O) is absolutely mandatory, though. Saying complexity analysis is "pretty much meaningless" is the dumbest part of Mei's article. Kun also makes good points about recent innovations in DSP, machine learning, etc come from math--but only the *theory* part. You still need people good at the mechanics of programming to *implement* that theory in a productizeable way.

Programming isn't, strictly speaking, math. Not like calculus or algebra is math. It's something else entirely.

I have a rather annoying learning disability, and have suffered from it since I was in first grade: I have a great difficulty memorizing things. Now, even with that rather annoying problem, I managed to be near the top of the class in both grade school and high school. What happened is I learned early on how to analyze the patterns behind the subjects I was expected to memorize and when test-time came was able to reconstruct most of the required information based on those patterns. Perfect example of this is spelling. I figured out what phoenetic combinations ruled English, and used them to pass tests. Armed with those rules, I only had to remember one or two odd words per week. In history, I found myself being able to understand and explain historical trends and influences. Names and Dates, on the other hand, gave me (literally) a headache. Simple math was easy (just a small number of consistent rules, after all). Sort of. Word problems in math, on the other hand, were difficult at best.

After I graduated college, I bought myself a Commodore 64 (they were just on the market) and dove right into both Basic and Assembly language. Both were easy for me to analyze and comprehend. Logic may be a branch of mathematics, but to me it's more obvious than anything in the math textbooks. Calculus is (for me) as obtuse and illogical as it gets. "If a water tank with a height of 15 feet and a circumference of 20 feet is 2/3 full of water, with a 1/8 inch hole a foot above the bottom, how long will it take the water level to drop to the hole?" Just plug the hole, whydoncha? Jeez!

Interestingly enough, I also have problems with computer word problems. Just give me the code (any code -- C, C++, C#, pascal, basic, assembler, SQL) and a little time, and I'll tell you what's causing the bug you're seeing. Now, after all these years, I'm the one everyone comes to when faced with an intractable computer problem that no one else seems able to solve. And I still don't like math.

## Programming != Mathematics (0)

## Anonymous Coward | about 4 months ago | (#47487279)

This is a debate between people without an education or picked up knowledge in mathematics vs. those who do. People who don't, like me, are perfectly happy finding well-paid senior-level positions which do not require in-depth experience of optimized algorithms in C or similar. People who have found an interest in math and who work in specific sections of the industry where the knowledge in math is a necessity may lean towards thinking about "programming" as only being related to the *same work* they perform. Just because a particular job requires a specific skillset does not mean the entire industry requires the same set of skills.

Where does the notion that being a programmer or developer is akin to becoming a structural engineer? Building a bridge properly requires a very specific set of skills; programming does not. And no, I'm not talking about the person who spends a few months copy/pasting php snippets with google's help - we're talking about people who have spent years developing their craft, *after* formal schooling has ended.

I started between ages 10-12 on geocities, finally figured out what the hell CGI programming was (I'm nostalgic for those mailto: form actions), and have since progressed to being a senior developer. I would put myself in the 80-90th percentile of backend web developers and 50-70th percentile on frontend. I have only met 3 other web developers in 10 years who actually put in the effort to understand the technology they are working with the same way I do. It's frustrating to deal with software engineering graduates with 5+ years of experience on a daily basis, who don't know the difference between a 301 and 302 http redirect, why their CDN isn't caching (set cache headers...), dealing with complaints about the difficulty of understanding ternary syntax, or explaining why they can't instantiate an abstract class.

If you want to segregate developers, don't do it on the basis of mathematical and algorithmic logic. Do it based on people who have a thirst to learn (and who actually accomplish this) vs. those who only got into the industry for the money. You can tell the difference between the guy who spends at least some of his free time picking up new skills vs. the one who shows up 9-5 then completely drops everything developer-related until 9am the next day.
