Algebraic Expression

An algebraic expression is a valid combination of numbers, variables, and mathematical operations. For example, in the expression the variable is being multiplied by its coefficient and this product is then added to the constant
The figure illustrating the components of an algebraic expression, such as 2x+3. In this representation, 2 is the coefficient, x is the variable, and 3 is the constant term.
Algebraic expressions come in many forms. They can be monomials, like the in the binomial above expression. In a polynomial, each monomial separated by a or sign is called a term.
An entire polynomial, like the above trinomial, is also called an algebraic expression. However, an expression that only contains constants is called a numerical or numeric expression.
