Welcome to my Graphical Universal Mathematical Expression Simplifier and Solver (GUMESS).

Enter expression to be simplified, or equation to be solved. GUMESS will figure out if what you typed is an equation.

Note: this simplifier is an work in progress. Use it at your own risk. It is likely to work correctly, however, it may not do all necessary simplifications. I have a large library of test cases that I test before releasing new versions. Right now it does the following: reduction of constants, removal of unneeded parentheses, reduction of similar factors and terms, linear equations, quadratics, some polynomial reductions, associative property, some substitutions.
You must use the "*" (star) symbol for all multiplications! x(x+1) is WRONG! It means a function x of x-1. x*(x-1) is right. Use the ^ (caret) for exponentiation. x^2 means x squared. x/2y means x/2y
