# Simplifier Tool for Windows

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 $a+(1/2)$. –  Michael Hardy Oct 8 '11 at 14:49
Actually that's only true if you assume that $a\neq0$. –  FUZxxl Oct 8 '11 at 14:52
Another way of putting Michael's comment: parentheses are cheap. Use them when there is a potential source of ambiguity. –  Ｊ. Ｍ. Oct 8 '11 at 14:53

Mathematica has the command FullSimplify, for example. One can use it for free on WolframAlpha; here it is in action simplifying $\frac{a(a+1)}{2a}$ into $\frac{a+1}{2}$.

Is there any desktop software or plugin? –  ARZ Oct 8 '11 at 16:09
matlab can do this, by using sym method. –  ofer Oct 8 '11 at 16:23
There are both mobile apps and widgets: products.wolframalpha.com –  Raphael Oct 12 '11 at 10:35
