Press the flag, type in the equation, see the line/parabola drawn. Don't use "y=" before the equation. This helps you with your math homework when you run into a quadratic. FOR A SQUARE, TYPE x**2, NOT x^2. This took me a while, so please love, favorite, and follow. I would suggest turbo mode.
IT WILL SIT THERE UNTIL YOU PRESS SPACE FOR YOU TO WRITE DOWN YOUR SOLUTION!!! Please comment if you find a bug. There is a bug where it won't draw lines if they are almost straight up and down. Also, the numbers might be slightly off like 10 might be 9.999999998. The equation will only work if you type it in the form "ax**2+bx+c", where a b and c can be changed. Use decimal form, not fraction form. 1 unit=1 pixel. If you want one square to be one unit, divide A by 30, multiply B by 30, and multiply C by 30.
