Doc's Super Math App Basic app for iPhone and iPad

Docs super Math App is a flash-card like app for learning arithmetic. The app allows the student to choose among the four basic operations of addition, subtraction, multiplication and division and to combine as many of those operations as desired. The app also allows for the use of signed numbers. In addition it has an option of using a constant factor in order to learn the “times tables” for multiplication.
Using random numbers, the app displays numbers and the chosen operation and the student is asked to enter an answer. If the answer is correct, the app displays another question; If the answer is incorrect the student is given a second and third chance to give the correct answer. If the correct answer has not been given after the third try, the correct answer is displayed for the student to see.
The app is designed for iPhone models 5s through iPhone X and all models of iPad. It requires iOS 9 or later.
