Absolute Value refers to how far a number is from 0 on a number line. |
| 2 | = ?
What is the absolute value of 2? Let's check on the number line:
Figure 1. |

Here, "2" is 2 points away from 0. So, | 2 | = 2.
How would we solve "| -3 | = ?". Again, we use the number line.
Figure 2. |

"-3" is 3 points away from 0. So, | -3 | = 3
The absolute value of any number is always positive.
