Answer:
-186
Step-by-step explanation:
When you add a positive number to a negative, it gets bigger (In value) . For example:
-5 + 4 = -1
-10 + 12 = 2
So for this equation, -200 + 14, all you have to do is subtract 14 from 200, which will get you 186.
Since you removed the negative, add it back to get -186
