Calculator How to use: Lets say you want to do 3+3. Click the CACULATE button. It should say "Which number?". Input "3" because it is the first number. Then, it should say "Which operator?". In this case it is a "+" because we are doing 3+3, but you can also do "-", "x", and "/". (The slash stands for division.) Then it should say "Which number?" again. We put in 3. It is the last number. It should then say your answer and it should also write your calculation in the list. Now you can start all over again.
