Question

Evaluate −9 − (−4).

5
−5
13
−13

Answer 1

-5, because subtracting a negative is the same as adding a positive, which will bring -9 up to -5

Answer 2

`-5`

Explanation:

We want to evaluate -9-(-4).

This is the same as
`-9+4`.

We can again rewrite this as
`4-9`

Since we are subtracting a larger number from a smaller number, the result will be negative.

Therefore our expression evaluates to
`-5`

The second option is correct.
