Read the Math Notes box for this lesson. Then simplify each of the following expressions.

$| - 15 | + | - 26|$
Hint (a):
Absolute value is the distance a number is from zero on the number line in either direction.
We use the special symbol shown below to indicate the absolute value of any number $x$ .
For example: The absolute value of any number is non-negative.
$|-3|=3\text{ and }|3|=3$
Answer (a):
$\left. \begin{array} { c } { - 15 | + | - 26 | } \\ { 15 + 26 = 41 } \end{array} \right.$

$- | - 40 |$

$| 0.5 | + | - 1 \frac { 1 } { 2 } |$
