Jase. Because it is further from zero and has the greatest absolute value.
Jarrod says the absolute value of 8 is -8. If any, what is Jarrod error and what is the correct answer?
Jarrod is thinking of opposites. Absolute value is the distance from 0 and always positive. The answer is 8.
The same distance from 0. 5 1/4
