  1. Absolute Value Distance from zero on a number line

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

  3. Absolute Value The distanceaway from zero -4 = 4 2 = 2 4 steps to 0 2 steps to 0 -4 -2 0 2 4

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

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

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

  7. Absolute Value Put your calculator in scientific mode Calculator Emulator Simplify: (3.2 x 107) – (4.8 x 108)

  8. Absolute Value Put your calculator in standard mode Calculator Emulator Simplify: (6.2 x 10-8) – (7.8 x 109)

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

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

  11. -10 -8 -6 -4 -2 0 2 4 6 8 Absolute Value x + 4 > 6 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

  12. -10 -8 -6 -4 -2 0 2 4 6 8 Absolute Value 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

  13. “Nothing yet. How about you Newton?”
