This is a quadratic formula calculator! Change a,b, and c by using the scrolls or by pressing the letter (a,b,c) on the keyboard to move up 1 and the letter to the left of it (p,x,v) to move down 1. The scoll only works with positive numbers so you will have to use the keys to get negative ones. Press space for the answer. If "Can't Solve " comes up it means that either a=0 or the number in the square root is negative. Scratch doesn't like imaginary numbers. In that case, just do it yourself. HAPPY CALCULATING
