I don't know the last one. And I'm having a hard time finding out, unless it's simply called "bar".

According to the CRC Standard Mathematical Tables 16th edition
p657, it is a "horizontal rule" or a "sign of division".

Another posting in that thread says:

As a boy I was taught to call it a "vinculum". The Collins Dictionary
of Mathematics may explain why: it's a "horizontal line placed above
a group of terms in an expression as an alternative to brackets..."

Interesting. And "virgule" is a good word too. :-)

I think I'll go with "horizontal rule". Now to see what my sister says it is.
