In elementary school, after you learn to count, you learn the basics of arithmetic. This is the branch of mathematics concerned with the relationships between numbers, measurements, and computation, among other things. The ancient Egyptians and Babylonians are credited with the earliest documented evidence of accounting using numerals and place values.
The word arithmetic ultimately derives from the Greek noun arithmos, meaning "number," with stops along the way in Latin, Anglo-French, and Middle English.
Even the simplest math has a deep vocabulary. The four primary arithmetical operations are addition, subtraction, multiplication, and division. In addition, one or more addends are combined to produce a sum. In subtraction, a subtrahend is removed from a minuend to produce a difference.
