Matrix Math: Solving Equations app for iPhone and iPad

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 for involving the solving of two equations simultaneously via matrices. This version solves these problems via the inverse method.
For students, provides self-paced practice of the steps required to solve two equations using matrices and the inverse method. Detailed help screens remind them of the strategy to solve two equations using matrices and the inverse method.

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!)
Requires IOS 8.0 or higher

Designed, built and tested primarily for IPhone 5, IPhone6 however works great on IPads.
