What is Arithmetic?
In [[mathematics]], '''arithmetic''' is the basic study of [[number]]s. The four basic arithmetic operations are [[Operation (mathematics)#Addition|addition]], [[Operation (mathematics)#Subtraction|subtraction]], [[Operation (mathematics)#Multiplication|multiplication]], and [[Operation (mathematics)#Division|division]], although other operations such as [[Operation (mathematics)#Exponentiation|exponentiation]] and [[Operation (mathematics)#Roots|roots]] are also studied in arithmetic.<ref>{{Cite web|date=2020-03-17|title=List of Arithmetic and Common Math Symbols|url=https://mathvault.ca/hub/higher-math/math-symbols/common-math-symbols/|access-date=2020-08-25|website=Math Vault|language=en-US}}</ref><ref>{{Cite web|title=Definition of Arithmetic|url=https://www.mathsisfun.com/definitions/arithmetic.html|access-date=2020-08-25|website=www.mathsisfun.com}}</ref><ref>{{Cite web|title=Arithmetic|url=https://www.britannica.com/science/arithmetic|access-date=2020-08-25|website=Encyclopedia Britannica|language=en-US}}</ref> Other arithmetic topics includes working with negative numbers, [[Fraction (mathematics)|fractions]], [[decimal]]s and [[Percentage|percentages]]. ==Overview== Most people learn arithmetic in [[primary school]], but some people do not learn arithmetic and others forget the arithmetic they learned. Many jobs require a knowledge of arithmetic, and many employers complain that it is hard to find people who know enough arithmetic. ==Applications== A few of the many jobs that require arithmetic include [[carpenter]]s, [[plumber]]s, [[Mechanical engineering|mechanics]], [[accountant]]s, [[architect]]s, [[doctor]]s, and [[nurse]]s. Arithmetic is needed in all areas of mathematics, [[science]], and [[engineering]]. Some arithmetic can be carried out mentally. A [[calculator]] can also be used to perform arithmetic. [[Computer]]s can do it more quickly, which is one reason [[Global Positioning System]] receivers have a small computer inside. ==Examples== * <math>2+3=5</math> (addition is [[commutative pr
