Let us learn some vocabulary Examples

Absolute value Evaluate: |5| 5 UNITS

Numbers that are the same distance from zero have
the same absolute value.
5 UNITS 5 UNITS -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6
| 5 | = 5 The absolute value of 5 is 5 units
from 0

-6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 Answer 5

Key Concept Evaluate: |–8| + |–1|

|–8| + |–1| = 8 + 1The absolute value of
-8 is 8.
Absolute Value The absolute value of
-1 is 1.
Words: The absolute value of a number is the = 9 Simplify
distance the number is from zero on the
number line. The absolute value of a
number is always greater than zero. Answer 9
