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 addition, subtract and multiplication of 2X2 and 3X3 matrices.
For students, provides self-paced practice adding, subtracting and multiplying the values within 2X2 and 3X3 matrices. Detailed help screens remind them of the strategies for each operation. For each problem displayed, if they answer incorrectly, a hit to its component parts is displayed.
The app provides for 4 timing modes including untimed (the default) and 1, 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!)
