What is a coefficient in an algebraic expression?

Back

A coefficient is a numerical factor that multiplies a variable. For example, in 2x, 2 is the coefficient.

Front

What is a variable in an algebraic expression?

Back

A variable is a symbol (usually a letter) that represents an unknown value. For example, in 2x, x is the variable.

Front

What is a power in an algebraic expression?

Back

A power indicates how many times to multiply the base by itself. For example, in 4², 2 is the power.

Front

What is an exponent?

Back

An exponent is a number that shows how many times the base is used as a factor. For example, in 3³, 3 is the base and 3 is the exponent.

Front

What is a numeric expression?

Back

A numeric expression is an expression that contains only numbers and operations, such as 100 - 12² + 5.

Front

What is an algebraic expression?

Back

An algebraic expression is a combination of numbers, variables, and operations. For example, 2x + 3 is an algebraic expression.

Front

What does it mean to simplify an expression?

Back

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

Front

What are like terms?

Back

Like terms are terms that have the same variable raised to the same power. For example, 2x and 3x are like terms.
