QUESTIONS
1. Think about |-4 | times 5. Is this greater than, equal to, or less than 10?
2. On a number line, put a dot to represent each of the following numbers: 7,4, -2, -8, and |-5 | . What is the median of this set of numbers? (If necessary, see the "Mean, Median and Mode" section under the "Other" part of the menu at the top of the page.
3. Evaluate (-20) times | 17 - 43| .
4. What is the value of minus |7 | ?
5. Simplify 3 |53 - 42|.
ANSWERS
1. The |-4 | x 5 = 4 x 5 = 20. 20 is greater than 10.
2. The numbers become, in order, -8, -2, 4, 5, and 7. The median is the middle number, which is 4.
3. The second term is | 17 - 43| = |-26| = 26. Then -20 x 26 = -520.
4. Minus 7. The |-7 | is 7, to which you then apply the minus.
5. 3 |53 - 42| = 3 |9| = 27.
