Warm-Up -8 7 = 4 x (-8) = -6 x (-6) = 48 / 8 = 9 12 = -66 / 6 = Absolute Value Definition A numbers absolute value is its distance from 0 on a number line. Really big deal about Absolute Value: Since distance can never be negative, absolute values are never negative. They are always positive or zero. Use a number line to find each absolute value. |8| 8 7654 32 1 0 8 units 8 is 8 units from 0, so |8| = 8. The symbol is read as the absolute value of. For example -3 is the absolute value of -3. Reading Math Use a number line to find each absolute value. |12| 12 11 10 9 8 7 6 5 4 3 2 12 is 12 units from 0, so |12| = units Evaluate the absolute value: Ask yourself, how far is the number from zero? 1)| -4 | = 2)| 3 | = 3)| -9 | = 4)| | = Evaluate the absolute value: Ask yourself, how far is the number from zero? 1)| 12 -4 | = 2)| 3 15 | = 3)| | - 1 + 2 = 4)| | + = Try a few more:
