Algebraic expression definition
Hunter-Best [27]

Answer:

A mathematical equation or phrase that includes numbers, variables, and operators.

Step-by-step explanation:

Examples of numbers: 1, 5, 60, 100

Examples of variables: a, x, y

Examples of operators, +, -, x, /

Any mathematical equation with all 3 of the given examples is called an algebraic expression.

For example:

1 + 21 is not an algebraic expression, because although it has both numbers and operators, it does not have a variable.

x + 2 is an algebraic expression, because it has all 3 of the components listed above.
