Description
A variable (pronounced /ˈvɛəriəbəl/; VAIR-ee-ə-bəl) is a symbol that stands for a value that may vary; the term usually occurs in opposition to constant, which is a symbol for a non-varying value, i.e. completely fixed or fixed in the context of use. The concepts of constants and variables are fundamental to all modern mathematics, science, engineering, and computer programming.[1]
