I have to code an app like this for android. Where an equation gets generated and the user has to pick/touch one of three answers below.
Couple of questions:
When I generate the equation, I guess I create a method for Addition and one for Subtraction where I can have an array of 0-9 for the first number and same for the second number.
Then have a sum = number1 + number 2 or -
Then randomly generate 2 numbers for the answers and the sum as the 3rd one.
Any thoughts on where I begin?
