Math 42 is a neat iPad app that I tried earlier this week. The app is one part calculator and one part mathematics tutorial. When students enter an equation into Math 42 they not only receive the answer they also receive a break-down of the steps needed in order to solve the equation. Along with an illustration of the steps students can see alternative approaches to solving a problem.

Math 42 is designed to handle mathematics problems commonly found in math curricula for fifth through twelfth grade. Math 42 works offline and does not require students to register for the service.
