Introduction to Combining Like Terms

What are terms separated by in an expression?

• addition

• subtraction

• multiplication

• division

• all of the above

What are the terms in this expression?

7b + 5

• 7, b, 5

• 7, 5

• b

• 7b, 5

What are the terms in this expression (not simplified)?

6v - 4v + 9b - 2

• 2v, 9b, 2

• 6v, 4v, 9b, 2

• 10v, 9b

• v, b

What are the terms in this expression?

(100 + 47 + 9) / 6r

• 100, 47, 9, 6r

• r

• 6r

Is the 6b in this expression positive or negative?

7b - 6b + 2b - 3b

• Negative

• Positive

If you want to combine terms, do the variables have to match?

Ex: 5g + 6g = 11g

• YES, the variables must match exactly

• NO, the variables don't matter

Combine these terms:

3r - 2r + 5r

• 10r

• 0

• 6r

• 7r

Combine terms with the same variable only!

4f - 2f + 6 + 10

• -2f + 16

• 6f + 16

• f + 6 + 10

• 2f + 16

Combine terms with the same variable only!

3r + 5v + 2s + 6b

• You can't! None of the variables are the same.

• 16rvsb

Combine like terms:

-5 + (-2) + y + 7y - 9

• 8y - 16

• 16 + 8y

• -16 - 6y

• -8y
