Front

What is the process of simplifying an expression?

Back

The process of simplifying an expression involves combining like terms and reducing the expression to its simplest form.

Front

What are like terms in an expression?

Back

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

Front

Simplify the expression: a + a + g + k + a + b + g + h + b + g – h

Back

None of the above.

Simplify the expression: 4b + 9 + 3b – 5b – 5 + b

Back

3b + 4.

Front

Simplify the expression: 2a + 3a + 5a – 4a – 2a

Back

4a.

Simplify the expression: 4g + 3g + 2g + g

Back

10g.

Front

What is a coefficient in an algebraic expression?

Back

A coefficient is a numerical factor that multiplies a variable. For example, in 4a, 4 is the coefficient.

Front

What does it mean to combine like terms?

Back

Combining like terms means adding or subtracting the coefficients of terms that have the same variable.
