Example 3.6 from Prealgebra, 3.1 Introduction to Integers

Introduction to Integers: example 3.6

Simplify:

ⓐ $| 3 |$
ⓑ $| −44 |$
ⓒ $| 0 |$

Work it out on paper first. Then open the solution one step at a time, and stop as soon as you can finish on your own.

Solution

ⓐ

$| 3 |$

3 is 3 units from zero. $3$

ⓑ
$| −44 |$

−44 is 44 units from zero. $44$

ⓒ

$| 0 |$

0 is already at zero. $0$

Your turn

The book's Try It right after this example: same idea, new numbers. Only the answer is given.

Simplify:

ⓐ $| 12 |$
ⓑ $- | −28 |$
