Once you press the green flag you have to pick an operation(Addition, Subtraction, Multiplication, Division). It will give you an expression that goes with the operation you picked. You have to answer it and if you get it right then you move forward if you get it wrong you move backward. You are trying to get to the finish line. If one of the other cars gets there first you lose.
In this game, you can practice the basic operations. Good luck!
