Hi there!

I believe your answer is:
A. - 31 - 71 = - 102
B. - 9 + 14 = 5

Here’s why:
⸻⸻⸻⸻
A. The minuend, subtrahend, and difference are parts of a subtraction problem. In the subtraction problem, - 31 - 71 = - 102, the number - 31 is the minuend, the number 71 is the subtrahend and the number - 102 is the difference.
B. When you are adding a negative number to a positive number you are effectively subtracting the second number from the first. ... And then you add the negative number, which means you are moving to the left – in the negative direction.
⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.
