When it asks you, "Function", type in +, -, *, /, sin, cos, tan or squareroot. If you type in +, -, * or /, type in the first number in the equation. When it asks you, "Second?", type in the second number. A smiley face will appear and say the answer. If the function in sin, cos, tan or squareroot, type in the number that you want that function to happen to. Again, a smiley will appear and say the answer. When the smiley disappears, it will ask, "Function?" once again. Also, if you type in pi, it will show pi to the 59th (I think) decimal place.
I made this project by using the +, -, *, /, sin, cos, tan and sqrt operators and by using variables for the numbers in the equations.
