Notes: To type a decimal point, click on the green dot sprite. The nth root: the first value is the starting value, and the second value is what type of root it is (square root, cube root, etc.) I am pretty sure I took the formula from the Scratch Wiki for this one. The hollow shapes are perimeter functions, and the filled shapes are area functions. Some shapes such as the square root/circle functions do not require both values to be filled. (Type the diameter for the circles.) The exponent function is completed by typing the base first and then the power. To type pi, click the left arrow, then the up arrow, then the right arrow.
