The following is the definition and operation of rational numbers a and B: a # B = A-B + 1. Is a # B equal to B # a? Why? Thank you
I know it's not equal. Mainly, I want to know how to write the reasons. The reasons are written by examples. Thank you

a#b=a-b+1
b#a=b-a+1
If we want to prove whether a # B and B # a are equal, we can prove whether A-B + 1 and B-A + 1 are equal
We can prove whether A-B and B-A are equal
a-b=-(b-a)
We can prove whether - (B-A) and (B-A) are equal
When a = B, B-A = 0
a-b=b-a
When a ≠ B is, B-A ≠ 0
a-b≠b-a

A is negative 3, B is 0, C is 2. There are several ways to move two points in ABC so that the number of three points is the same
