Mental Math Extreme's support info

Mental Math Extreme is a simple app.

There are only few settings you can apply.

App changes between dark and light modes based on the system settings.

In the settings screen - which shows after the app is loaded - you can adjust difficulty.

From and To fields indicate the range of numbers A, B available for generating addition (A+B), subtraction (A-B) and multiplication(A*B), division (A/B) questions respectively.

Subtraction questions would always result in no-negative answer.

Division questions would always result in non-negative integer answer.

Because for a given range results of multiplication and division can be large (e.g. for the settings below we can get 99*99 = ? question), we give users option to limit possible results up to a given number. E.g. for the settings below, if we have A*B = C, we guarantee that C will always be below or equal to 1000.

Duration in sectionds is a picker elements which sets the length of the game.
