Question

Which expression does not belong with the other three? Explain your reasoning. |3| -3 |-3| 3

Answer 1

-3.

Explanation:

That would be -3 because it is negative.

|3| 3 and |-3| are all positive.

|-3| means the absolute value of -3, which is positive.

Answer 2

`\huge\boxed{-3}`

All of the other expressions are equal to a positive
`3`.

Absolute value finds a number's distance from zero, which basically removes its negative sign if it has one, making the number positive.

`|3|=3`

`\boxed{-3=-3}`

`|-3|=3`

`3=3`
