Question

Which two values of n make this equation true?
`|n| = 3`

Answer 1

Absolute Value

The absolute value of a number x, denoted as |x| is defined as the positive (or zero) distance from the number zero to the number x.

In other words, the absolute value of any number is never negative.

For example:

|2| = 2

|0|= 0

|-1| = 1

|-2| = 2

Note the second and fourth examples give the same result, even if the original numbers were different.

This means that if we know that

|n| = 3

then, n can take two possible values, n=3 or n=-3
