a.
|40|= 40 bc the distance from 0 to 40 is 40
b. |-40|= 40 bc the distance from 0 to -40 is 40
absolute value for a negative number will always be the opposite and absolute value for a positive number will still be positive. for example the absolute value of -5 would be 5. the absolute value of 45 would just be 45. does that help?
