This math solver enables you to simplify, factor and expand expressions, find LCM (Least Common
Multiple) and GCF (Greatest Common Factor). Here are some hints on the
calculator usage:

if your problem contains =, < or > signs, you are on the wrong page.
Click on Equations or Inequalities menu item.

only sums can be factored and only terms (or powers) can be expanded.

multiple expressions need to be entered on LCM and GCF tabs. Make
sure you separate them with a comma (",").

If you need to find a LCD (Least Common Denominator), use the LCM page.
However, make sure you enter denominators only (not the whole
fractions!).

hover the mouse over the question marks for more detailed help.
