MMT is the Tutoring App for Addition and Subtraction. MMT currently uses the American Method. The Austrian Method will be provided soon.
The numbers to be added or subtracted are entered using a calculator format on the first page of the app.
After pressing the equals button, MMT will execute and explain the calculation step by step.
The back arrow will bring the user back to the first page, where the clear button can be used to begin a new calculation.
The explanation is available in English or German.
