Absolute Value Distance from zero on a number line

2
Absolute Value 5 = 5 The absolute value of 5 is 5 -5 = 5 The absolute value of -5 is 5

3
Absolute Value The distance away from zero 0-2-424 -4 = 42 = 2 4 steps to 0 2 steps to 0

4
Find the absolute value key on the HP 39G Absolute Value ABS

5
Simplify: 2-7 Absolute Value Simplify: 7-2 Calculator Emulator Simplify: - 7-2

6
Absolute Value Simplify: (2-7) 2 Simplify: -(2-7) 2 Simplify: - -(2-7) 2 Calculator Emulator

7
Put your calculator in scientific mode Absolute Value Simplify: (3.2 x 10 7 ) – (4.8 x 10 8 ) Calculator Emulator

8
Put your calculator in standard mode Absolute Value Simplify: (6.2 x 10 -8 ) – (7.8 x 10 9 ) Calculator Emulator

9
Solve: x = 4 Absolute Value What numbers work for x? 4 = 4 or -4 = 4 x could = 4 or x could = -4

10
Solve: x + 2 = 4 Absolute Value What numbers work for x? x + 2 could = 4 or x + 2 could = -4 x + 2 = 4 - 2 -2 x = 2 or x + 2 = -4 -2 -2 x = -6 2-6 Always check your answers

11
x + 4 > 6 Absolute Value x + 4 > 6 x + 4 could be bigger than 6 x + 4 < - 6 x + 4 could be less than -6 x + 4 > 6 -4 -4 x > 2 x + 4 < - 6 -4 -4 x < -10 0-2-4426-6-88-10

12
Absolute Value 0-2-4426-6-88-10 x + 4 < 6 x + 4 < 6 x + 4 could be less than 6 x + 4 > -6 x + 4 could be bigger than -6 -6 < x + 4 < 6 that means x + 4 could be between -6 and 6 -6 < x + 4 < 6 -4 - 4 -4 -10 < x < 2
