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 |
