The ultimate Scratch solution to those quadratics questions you have to do for maths but absolutely hate! Just enter the values for a, b, and c (it even shows you which one's which in case you're not sure), and the cats will tell you the possible values for x, or if there aren't any.
I'd like to acknowledge my friend Santa07, who gave me the idea for this project with his trigonometry programs (which I don't think he's uploaded yet) for the sine and cosine rules and area of a triangle. Don't be surprised if you see a studio dedicated to doing your maths homework for you with them inside.
