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 $a+(1/2)$.2011-10-08

    Actually that's only true if you assume that $a\neq0$.2011-10-08

    Another way of putting Michael's comment: parentheses are cheap. Use them when there is a potential source of ambiguity.2011-10-08
