Answer 1

Hi! i think your answer is C.

Explanation:

On a number line you would see that -5 is behind the zero. So The 3+ would mean you would add 3 to you negative number. But that dosent mean to add it like this (5+3=8). My biggest tip is to subtract what ever number there is. For example:

9 + (-10).

So it would mean -1!

I hoped this helped! <3
