8-91.

Recall that vertical lines around a number are the symbol for the absolute value of a number. Simplify each expression.

There cannot be a negative absolute value.

When a negative is outside of the absolute value symbol, it stays a negative.
When a negative is inside of the absolute value symbol, it becomes a positive, but do not confuse this with a minus sign.
Subtract the numbers first before finding the absolute value.

1. $|6|$

$6$

1. $| - 17 |$

1. $- | - 4.5 |$

$−4.5$

1. $| 2 - 5 |$

$3$

1. $| 2 - 3 \cdot 5 |$

1. $- 2 \cdot | - 2 |$

$−4$
