# Mathematics

Mathematics (from Greek μάθημα máthēma, “knowledge, study, learning”) is the science that deals with the logic of shape, quantity, and arrangement.

A discipline (an organized, formal field of study) such as mathematics tends to be defined by the types of problems it addresses, the methods it uses to address these problems, and the results it has achieved.
