Ninja Mathster builds a list of problems from 1 X 1 through 12 X 12 and randomly displays a problem. If the student inputs the correct answer in less than eight seconds, they don't have to repeat the problem. However, if it takes too long the app puts the problem back on the list and they will have to try again.

Tap + in the top right and select the type of problem you want to practice. It will create a new row. Tap the row to begin.

* Writing the problem and answer helps you remember it the next time you see it.
* Answer the questions until you complete the assignment.
