Math Matrix: Find the Inverse

This app is primarily designed for teachers and students of math. Usually covered in an Algebra 2 or PreCalculus class.

For teachers, allows them to easily generate sample problems involving finding the inverse of a 2x2 matrix.

For students, provides self-paced practice finding the inverse of a 2x2 matrix. A detailed help screen remind them of the strategies for finding the inverse.

For each question displayed, if they answer incorrectly, a hint for the question is displayed.

The app provides for 2 timing modes including untimed (the default) and 2 and 5 minute testing modes. After the student has answered each question, the app gives them immediate feedback including the correct answer if they choose the wrong answer.

In all modes, the total number of question requested and the number answered correctly is displayed at the top of the screen.

Designed, built and field tested in co-operation with a high school math teacher (Thanks Keith!)
