the definition of variable expression in math terms A variable is a letter representing some unknown a variable always represents a number but it carries varying values when written in an expression By convention mathematicians usually assign letters not mandatory at the end of the alphabet such as x y and z to be variables
The definition of a variable expression is a mathematical phrase that contains variables and numbers combined together with any mathematical operations Some examples of An expression is a combination of terms that are combined by using mathematical operations such as subtraction addition multiplication and division The terms involved in an expression in math are Constant A constant is a fixed numerical value Variable A variable is a symbol that doesn t have a fixed value

In simple words a variable is a quantity that can be changed and is not fixed Variables are essential as they form a major algebra component We usually use x and y to express an unknown integer Definition Variable A variable is a symbol usually a letter that stands for a value that may vary Let s add the definition of a mathematical expression
A Term is either a single number or a variable or numbers and variables multiplied together An Expression is a group of terms the terms are separated by or signs Term is something that is being added together Factor is something that is being multiplied together Coefficient is a number that is being multiplied by the variable 2x 6x 14 The 2x 6x and 14 are terms because they are being added together 2 and x 6 and x are factors because they are being multiplied together 2 from 2x and 6 from 6x
