Hey Miranda!
Let me help you out...
First, keep in mind that they just put these negative signs to make the thing looks difficult to solve :)
Do you remember this:
Well this the same thing. We gonna multiply the two negative signs that are behind the parentheses together and make it plus sign
Here is how it works
![8-[-(-3)] =8 + (-3) =8 - 3 =5](https://img.qammunity.org/2018/formulas/mathematics/high-school/4fsle6bt0v9vemc29641v24hss1u68a72a.png)
The correct answer is option A (5)
Good luck with your studies, Miranda.
