Graphic arithmetics

Simon is not only doing Precalculus en Calculus, but also enjoys maths at all levels (see previous post about The Secrets of Sums). For example, we do some Dutch elementary school tests to make sure he can handle the arithmetic. Below is a beautiful example of how his mind works. The task was to find the number exactly between 36×36 and 38×38 on the number line. Simon immediately came up with a parabolic graph and said it couldn’t be 37×37, based on that graph. I think he can graph just about anything in the world 🙂
