Anything mathematical has to do with the science of numbers and shapes, or is as precise and exact as a mathematical calculation.
If you weigh your new puppy's food on a digital scale each morning, you can say you're feeding her with mathematical precision. And when you work on problems in algebra class, you're most likely using mathematical formulas to solve them. Mathematical is derived from the Greek mathēmatike tekhnē, "mathematical science," and its root, which means "to learn."
