Double Negatives and Absolute Value Think of the – as opposite What is the opposite of 5? What is the opposite of -5? Therefore: -5 = negative 5, -(-5)= 5 So . . . When we see a Double Negative (right next to each other) we make it a positive

Double Negatives and Absolute Value Another way to think of it . . . When a bad thing happens to a good person, that’s bad  - 4 = -4 When a good thing happens to a bad person that’s bad  + (-4) = -4 When a bad thing happens to a bad person, that’s good  - ( - 4) = 4

Double Negatives and Absolute Value Is a #s distance from 0 This answer is ALWAYS positive Whenever you see these brackets I I whatever the answer is inside is ALWAYS POSITIVE!!!!!!!!!!!

Double Negatives and Absolute Value Examples: How far away is 6 from 0? What is the Absolute Value of 6? How far away is -6 from 0? What is the Absolute Value of -6? How far away is -3 from 0? What is the Absolute Value of -3?

Absolute Value Practice I 5 I = I -4 I = I 90 I = I -45 I = - I 4 I = I -4 I = - I 7 I - I 34 I =
