Absolute Value Examples

Example 1

|-3| + |2|

Treat absolute value bars as parentheses; do what is inside first.  Take the absolute value of (-3) and add to that the absolute value of (+2).

Example 2

-|-6|

Treat absolute value bars as parentheses; do what is inside first. Take the absolute value of -6, then take the negative of that number.

Example 3

|7 - 9|

Again, treat absolute value bars as parentheses, do what is inside first, then take the absolute value.

Example 4

|-5 + 3| - |-2 - 1|

Treat each set of absolute value bars as a set of parentheses. Simplify each separately, then subtract.
