A variable expression or an algebraic expression is a combination of terms by the operations such as addition subtraction multiplication division etc.
Definition of expression in math with example.
In mathematics an expression or mathematical expression is a finite combination of symbols that is well formed according to rules that depend on the context.
An example of a mathematical expression with a variable is 2 x 3.
This math operation can be addition subtraction multiplication and division.
Like terms are terms that have the same variable part i e.

An expression is a mathematical phrase that combines numbers and or variables using mathematical operations.
Illustrated definition of expression.
All variables must have a coefficient a.
An expression can be arithmetic algebraic polynomial and analytical.
In these lessons we will learn what variables constants terms expressions and coefficients are in algebra.
For example the formula for the area of a circle a π r2 gives the dependent variable a the area as a function of the independent variable r the radius.
An expression is a representation of a value.
They only differ in their coefficients.
Many widely used mathematical formulas are expressions of known functions.
Definition of expression in mathematics the expression is defined as a phrase that groups together numbers constant letters variables or their combination joined by operators to represent the value of something.
In algebra we begin to see variables or letters that are used to represent numbers.
An algebraic expression consisting of two or more like terms can be simplified by combining like terms.
