With the middle set button, you can enter in different modes, such as "multiply", "divide", "add", and "subtract". Press the left or right "set" button to set the first/second number. Press "equals" and it says the answer. Please star if you enjoyed this project. Thanks! -----------------------UPDATES------------------------------- 1.0 -- Normal 1.2 -- Squaring Buttons: when you press the "2" next to the variable(s), the equals button says the answer.
The green buttons do not work. Thank goodness for operators... I made this all by myself.
