IDK

OpenStudy (mathstudent55):

You just said it's the magnitude without the sign. |-6| = 6 The absolute of zero or a positive number is just the number. The absolute value of a negative number is just drop the negative. |0| = 0 |5| = 5 |2.86| = 2.86 |-5| = 5 |-1.239| = 1.239

OpenStudy (mathstudent55):

You have x = |-6|, but |-6| is imply 6, so x = |-6| means x = 6
