**Convert the following into an algebraic expression.**

Identify the operation(s) key word(s): less than, plus, sum, etc. Three plus A Answer: 3 + A A

4

six decreased by Y y Answer: 6 - y

5
Let’s Try Another One Convert the following into an algebraic expression. Six less than Y 6 - Y

6
Actually… 6-y is incorrect! The phrase states “six less than y” meaning six “taken away from” y, therefore the correct algebraic expression is……. Y - 6
