Matematyk (The Mathematician)

Why is this dwarf frowning? What kind of question is that? This is Matematyk, one of the most intelligent dwarves in the world. He analyzes, multiplies and adds, raises to the power of x and calculates the area of a triangle! A wrinkle on his forehead is a good sign! This maverick mathematician piles up fractions, simple and complex, although percentages pose a slight challenge, everyone knows he can solve any problem, calculate carefully and give the correct answer. And then his brow smooths out.
