3-128.

Evaluate each absolute value expression below.

Absolute value means distance away from zero on a number line.

Consult the number line below. How far is each value from 0?

1. $| 2 | + | 4 |$

Since $2$ and $4$ are already positive, just add.

2. $| - 3 | + | 5 |$

How far is $-3$ from 0?

|−3| = 3

|5| =5

3 + 5 = 8

3. $| - 7 | + | - 1 |$

4. $- | 6 |$

− 6
