I can't see a button for that anywhere :(

So that for example in 1/2 the "/" would be a horizontal line.

There's no button. It's LaTeX. Have a look at the LaTeX Primer.

You use $\LaTeX$, for which see the guidelines: (point 6)

($\TeX$ commercial:)

It's so easy ! just put $or  around the expression to get$LaTeX$. So (aB/2)t^2 + vB(initial)*t - vA(initial)*t + xBi = 0 becomes (aB/2)t^2 + vB(initial)*t - vA(initial)*t + xBi = 0 Then: superscripts come with ^ and subscripts with _ and grouping goes with curly brackets {...} You learn from other posts with a right-click on the formula and picking Show Math as ...$\TeX$commands. For your question: \frac {a+2} {b} gives$ \frac {a+2} {b} $and {1-2-3\over 4-5-6} gives${1-2-3\over 4-5-6} ##

 by the way: !! And don't hesitate to post whatever. We are used to imperfection (we only strive for perfecetion )

 perfection (unintended, but fortunate typo -- I like having it there )

Thanks a lot to everyone for the info! I have used LaTeX before, I'll have to try to recall how to use it...
