Question

absolute value & opposite integers - level 1
opposite integers are the same distance from zero but in the opposite direction. for example, +4 is the opposite of -4.
absolute value is the distance from zero on a number line. absolute values are either positive or zero. for example, the absolute value of -5 is 5. bars on both sides of a number, for example, |3|, mean the absolute value.

1. what is the opposite of +10? ____
2. what is the opposite of -4? ____
3. what is the opposite of +8? ____
4. what is the opposite of -1? ____
5. what is the absolute value of +13? ____
6. what is the absolute value of -8? ____
7. what is the absolute value of +1? ____
8. what is the absolute value of -40? ____
9. what is |-20|? ____
10. what is |+1|? ____
11. what is |-9|? ____
12. what is |+100|? ____
13. what is |-4|? ____
14. what is |0|? ____
15. what is |-36|? ____

Explanation:

Step1: Recall opposite - integer rule

Opposite of a positive integer is negative and vice - versa.

Step2: Recall absolute - value rule

Absolute value of a number \(n\), denoted as \(|n|\), is the non - negative value of \(n\). If \(n\geq0\), \(|n| = n\); if \(n<0\), \(|n|=-n\).
