What is a term in an algebraic expression?

Back

A term is a single mathematical expression that can be a number, a variable, or a combination of both. For example, in 3x + 2y + 7, there are three terms: 3x, 2y, and 7.

What is the difference between a variable and a constant?

Back

A variable is a symbol that represents an unknown value, while a constant is a fixed value. For example, in 3x + 5, x is a variable and 5 is a constant.

Identify the variable in the expression: 3x + 2y + 7

Back

x and y are the variables.

Front

What does it mean to simplify an algebraic expression?

Back

To simplify an algebraic expression means to combine like terms and reduce it to its simplest form.

Front

What are like terms in an algebraic expression?

Back

Like terms are terms that have the same variable raised to the same power. For example, 3x and 5x are like terms.
