Which number has the greatest absolute value?

a. 0

b. 10

c. - 10

d. - 20?

Keep in mind, absolute values are always positive, even when they say negative. That is because the absolute value of a number is just the distance that number is from 0. Example : - 5 and 5 ... they are both 5 spaces from 0 ... doesn't matter if it is negative or positive, it is still 5 spaces.

|0| = 0

|10| = 10

|-10| = 10

|-20| = 20

so ur answer is : | - 20 |
