Etymology
Origin of mathematics
1350–1400; Middle English mathematic < Latin mathēmatica ( ars ) < Greek mathēmatikḕ ( téchnē ) scientific (craft), equivalent to mathēmat- (stem of máthēma ) science, knowledge + -ikē, feminine of -ikos -ic; see -ics
Explanation
Mathematics is the long word for "math," or the science of numbers and shapes and what they mean. Most people need mathematics everyday to count and measure. Mathematics is technically a plural noun — mathematics include geometry, algebra, and calculus. But in the U.S., the word is usually treated as a singular concept: That's why someone says that mathematics is their favorite subject, not mathematics are their favorite subjects. The word mathematics comes from the Greek word manthanein, meaning "to learn."
