# (1/2x + ... = ?, Calculators that Crush Challenging Math Problems

The World Wide Web is a great source for online calculators. Some of these calculators are much more powerful than your typical desktop calculator. They show you not only the answer to your problem but also the step-by-step process used to get to that answer.

If a student is not sure how to do a math problem these calculators can help…*but*…there is often more than one way to solve a problem. A teacher may show a different method of solving a problem.

These calculators cover different subjects and work in different ways. Choose the one you like best.
