Answer:
-2
Explanation:
1) First, we conclude that the "-" in (-5) cancels out the "+"
2) Now we can write the equation as "3-5"
3) 3-5=-2
4) So let's plot this. I'll do the best I can using a keyboard.
(-5)---(-4)---(-3)---(-2)---(-1)---0---1---2---3---4---5
+
So let's start at -5. My little pointer will be a +
(-5)---(-4)---(-3)---(-2)---(-1)---0---1---2---3---4---5
+
To add, you move to the right. So let's add 3 by moving 3 spaces to the right.
And, there, you're at -2! Hope this helps.
