Question

3-(4-4)+4 is what ? i confused about if when u do the 4-4 that zero then what do you do next?

Answer 1

The answer is -1

Explanation:

First you need to follow the PEMDAS rule.

The negative is outside the parentheses which you would distribute. The first 4 becomes negative while the second for becomes positive. The problem is then 3-0+4 which the wether you add the 4 to 0 or subtract the 3 from 0 you will still be left with 3-4. The zero is more of a distraction when simplifying.

Answer 2

Answer:
`7`

Subtract

`4-4=0`

New Problem:
`3-0+4`

Remove 0

Before:
`3-0+4`

After:
`3+4`

Add

`3+4=7`

Note: You remove 0 because your just subtracting 3-0 which is still 3. Therefore you can just remove 0 and forget about it. After you remove 0 you can just add 3+4.
