Word: math

Interpretation: The science of studying quantitative relations and spatial forms in the real world. It is produced and developed in the long-term practical activities of human beings. Originated from counting and measurement, with the development of productivity, there is an increasing demand for quantitative research on natural phenomena; At the same time, due to the development of mathematics itself, it has a high degree of abstraction, strict logic and wide applicability. Now it can be roughly divided into basic mathematics (also called pure mathematics) and applied mathematics. The former includes mathematical logic, number theory, algebra, geometry, topology, function theory, functional analysis and differential equations. The latter includes probability theory, mathematical statistics, computational mathematics, operational research and combinatorial mathematics.
