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 then, this product is added to the constant
Algebraic expressions come in many forms; they can be monomials, like the in the binomial expression above. In a polynomial, each monomial separated by a
sign is called a term.
An entire polynomial, like the trinomial above, is also called an algebraic expression. However, an expression that only contains constants is called a
