Answer 2

If you are subtracting one quantity from another, the starting amount is called the minuend; the amount subtracted from it is called the subtrahend. The result is called the difference. In practice, the terms "minuend" and "subtrahend" are rarely used outside of the classroom. So to simplify it:
minuend - subtrahend = difference.

It is the number being taken away from in subtraction: minuend-subtrahend=difference.
