Lesson 20: Math Calculator
This project illustrates an interactive application where random addition problems are created. The user enters the expected solution and later is able to check its accuracy. It illustrates how to create multiple problems randomly, how to get input from the user, how to display this input on the screen and how to check the correctness of the input. It can be expanded to implement other operations and extend the range of final results.
