Answer:
The answer is 0.
Step-by-step explanation:
When you add (positive) 12 to (negative) -12, they cancel each other out since not only are they on exact opposite sides of the number line, given that they are the same number. So, the answer is 0.
Hope this helps!
The result of adding 12+-12 would always end up as 0 because, when you add a positive to a negative you would reverse the concept
