Variable Definition in Maths. In Algebra, a variable is an alphabet which is used to represent the unknown number. It represents the value. A variable is a quantity that may be changed according to the mathematical problem. The generic letters which are used in many algebraic expressions and equations are x, y, z.

Variable Definition In Mathematics, an algebraic expression is an expression which consists of the combination of variables, constants, coefficients, fundamental operations such as addition, subtraction, multiplication and division.

In ancient works such as Euclid's Elements, single letters refer to geometric points and shapes. In the 7th century, Brahmagupta used different colours to represent the unknowns in algebraic equations in the Brāhmasphuṭasiddhānta. One section of this book is called "Equations of Several Colours". At the end of the 16th century, François Vièteintroduced the idea of representing known and unk…

In mathematics, a variable (from Latin variabilis, "changeable") is a symbol and placeholder for (historically) a quantity that may change, or (nowadays) any mathematical object. In particular, a variable may represent a number, a vector, a matrix, a function, the argument of a function, a set, or an element of a set.
