When a problem uses difference they are dealing with subtraction, the question is asking what minus what will equal 1. Therefore your answer is 2 and 1

Subtraction is definitely an operation defined on real numbers. I'm guessing you are actually asking why subtraction is not included as a commutative operation, this is because a-b is not always equal to b-a.
17-9 could be a score not a subtraction problem word
If I remember correctly this is a straight subtraction problem. 189 - 80 = 109 wpm ========

Yes it does. Because the it acts like subtraction, but since the positive, negative number scales run backwards like a mirror, subtraction is addition with two negative numbers.
Divide the first two of the same three numbers by eachother, and then add the third same number to the answer you get.
