# Options for Adults with Renewed Interest in Math?

#### Cliff posted more than 11 years ago | from the back-to-school dept.

Internet Ninja asks: *"After only doing mathematics in high school level and in my first year of University, I've suddenly developed an interest in mathematics. Since that was now almost 10 years ago I'm a little rusty. Anything past pythagoras is a little tough for me :) but I know I could get back up to speed quickly. I could probably steal my daughters math textbooks and start reading but I'm wondering if there is a better way. I considered a part-time University paper at US$495 each and you need to do two as bridging courses in order to even start on undergraduate courses. A bit pricey when you have a home and family to look after as well. Another option was a night courses but I'm kept pretty busy with work. Does anyone have any advice or good resources?"*

I never had difficulty learning the examples. I could do any problem pretty much that relied on the examples in the book. When I needed to apply something else that wasn't taught to the T in the book I had a bit of a hard time w/that.

Math for me is something that would have to be taught in a classroom not from a book.

and unless you want to be a mathematician, or research engineer, the best way to go.

to quote an engineer at our Institute of Technology (which does research for gov't projects, high level stuff) "why are you taking calculus classes at "-my university-"? they're math department is horrible! go take them at "-the main community college-.

i personally couldn't get enough out of just reading a book. i wouldn't have the patience or self discipline to set a work schedule for them. so, i also suggest

finding an online course. even if it's not an accredited school, it's just a refresher really. good luck!## Community colleges (0)

I don't know where you are but I've never been to a place where a community college could compare to any but the weakest of universities. It's like VoTec or something. If you want a bunch of kids who are too dumb, lazy or cheap to go to a real college or university, go to a community college. Everyone there is basically bullshitting each other in to believing that they're getting the same education they would at a 'real' university.

It's basically all the credits, none of the work. To the original question: Go somewhere that will kick your teeth in and make you do the work.

Do you want this for information's sake, or do you want to plan a career out of it?

These questions are important because if you are doing it for education's sake, the first time you look into a college-level Multivariable Calculus book might result in a little voice giving you a sudden desperate need to close the book and never open it again.

Course, if you plan to make a career out of it, the above situation will probably still occur, but you'll at least have a strong reason to ignore that little voice and give it a serious try.

Personally, I was in a similar bind a few months ago. A co-worker was going to school for CIS and I read over his shoulder while he did his homework. More came back to me in those few months while watching him work and helping each other out than if I'd read the book by myself.

If you are hoping to learn enough to publish papers or contribute to the advancement of math, then I recommend taking the effort and getting a degree in mathematics (unless you are really, really good at math.

If you just want to have some fun with mathematical recreations. Scientific American released some great books with math problems, as well I know of a few others if you want them.

If you want to have some real fun and learn classical mathematics (no applied stuff), there's always Euclid's Elements and Mathematica Principia. But these books are definitely not for the faint of heart either.

If you want to learn math with a more applied edge, you can take night courses, or get a few good books on modern calculus or mathematics.

If you want to learn statistics, I feel really sorry for you.

If you want to learn comp sci related math, there are some fantastic books out there that will help (if you want details, just reply).

There is just so many areas to go into when you decide to mathematics again. It is hard to help you out with exactly what to do. I am taking a degree in math right now, but I can understand that with children that would be a difficult and strenuous challenge. Even though, I think it would be great to have another mathematician contributing to the body of math that exists.

The only suggestion I really have that may be quite helpful is to see if you can talk with any of the pure mathematics professors at the university or college near you. They might be able to help you find your niche in mathematics, and even provide you with some other alternatives not mentioned here.

It's really pretty old (1976) and there are probably tons of better options out there now, but I have on my shelves a book called "A Mathematical Journey" by Stanley Gudder. You can still find it on Amazon. It covers stuff like number theory, group theory, probability, graph theory. The computer science stuff is a little dated by now.

It's very much a text book so it has lots of excercies for the reader with answers in the back. I thought it was a good introductory treatment. I'm sure others will chime in with better suggestions, but that's mine.

Yes, you could get some textbooks and study on your own but unless you're extraordinarily disciplined you probably won't finish (I have a whole shelf of half-finished math books). Having the structure of a class (with homework) gives you a chance to ask questions and also helps you keep going when your initial enthusiasm wanes.

I say this having been both a math instructor and a math student who went back to school after several years working.

## Edmund Blackadder (559735) | more than 11 years ago | (#3810032)

But seriously university classes in math tend to be rather boring because they tend to reduce even complicated fields into a few formulas that can be memorized and a few problem types for which you can memorize which formula to use.

Also they tend to assign a lot of dull homework.

So classes seem to be geared towards those that cant understand math but are willing to tackle it with brute memorization.

Or maybe i just went to a bad university.

_How to Solve_ it by George Polya (anything by Polya is excellent)

These are classics written by famous mathematicians,

but they are not very advanced. They quickly get to

the "deep" and "beautiful" parts of their subjects.

of course to go on in math you will need command of

the important "every day" tools, esp. calculus and

linear algebra.

a good book for this is

_mathematical thinking: problem solving and proofs_ by

d'angelo and west. the first edition is better, if

you can find it

This one is a java-based demo of a bunch of signals and systems engineering math operations, at Johns Hopkins University [jhu.edu], and I wish more stuff like this could be available (especially from students working in specific areas) to help students of all ages grasp more complicated math. Or even simple math.

However, I'd be happy if more adults knew that p=mv so they wouldn't be so inclined to cut off a bus in their tiny cars as they both approach a stop light...
