Introduction
Look at the following examples to see how algebraic expressions can be used to represent word problems.
| Expression | Word Problem |
|---|---|
| a + 4 | 4 more than a |
| a - 4 | 4 less than a |
| 4 - a | a less than 4 |
| 4a | 4 times a |
| a/4 | a ÷ 4 or ¼ of a |
| 3a + 4 | 4 more than 3 times a |
| a/2 - 6 | 6 less than half of a |
