*** Instructions ****

Welcome to the multiplication game.
The game will ask you how many rounds you would like.
You will enter an integer between 1 and 10 and the computer will randomly generate an equation for you to solve.
You are to solve the equation where the program will tell ou whether your answer is correct or incorrect.
Try your best to get the answers right!

Good Luck!
