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.
