Simplifier Tool for Windows

Question

Is there any math formula reduction tools?

for example convert:

$\frac{a(a+1)}{2a}$

to:

$\frac{a+1}{2}$

Actually, it should be $(a+1)/2$, not $a+1/2$, since $a+1/2$ means $a+(1/2)$.
Another way of putting Michael's comment: parentheses are cheap. Use them when there is a potential source of ambiguity.

Two more ideas (free software for the desktop):

Maxima: a widespread free symbolic-math software; can even be configured to simplify wrt special trigonometric expressions (I use this if I have complicated expressions, derivatives and/or integrals)
(examples like yours above can even be handled by Pari/GP; but is not specialized on symbolic expressions and can simplify polynomial/series expressions, and -but only to a very small extent- rational functions. Likely not what you want)
