Arithmetic or arithmetics (from the Greek languageGreek word !''αριθ_ 6;ός''? = number) in common usage is a branch of (or the forerunner of) mathematics which records elementary properties of certain ''operations'' on numerals, though in usage by professional mathematicians, it often is treated as a synonym for number theory. It is the oldest and simplest branch of mathematics, used widely by almost everyone from simple daily counting to more advanced science and business.
Arithmetic operations - The traditional arithmetic operations are addition, subtraction, multiplication and division (mathematics)division, although more advanced operations (such as manipulations of percentpercentages, square root, exponentiation, and logarithmlogarithmic functions) are also sometimes included in this subject. Arithmetic is performed according to an order of operations. The arithmetic of natural numbers, integers, rational numbers (in the form of vulgar fractions), and real numbers (using the decimal place-value system known as algorism) is typically studied by schoolchildren, who learn manual algorithms for arithmetic. However, in adult life, many people prefer to use tools such as calculators, computers, or the abacus to perform arithmetical computations.
Number theory - The term ''arithmetic'' is also used to refer to number theory. This includes the properties of integers related to prime numberprimality, divisibility, and the Diophantine equationssolution of equations by integers, as well as modern research which is an outgrowth of this study. It is in this context that one runs across the fundamental theorem of arithmetic and arithmetic functions. ''A Course in Arithmetic'' by Serre reflects this usage, as do such phrases as ''first order arithmetic'' or ''arithmetical algebraic geometry''.
