5........is this really a question? when b=5, then b=5
Answer: Most likely there is always difference. Often A and B are describing unknown numbers. For example if A=10 and B=5. A-B = 10-5 = 5 B-A = 5-10 = -5 Answer: It can be any of these (most likely A - B), or it can be the absolute value of A - B (which is the same as the absolute value of B - A).

You can write that as 5 / (a + b), or as a fraction, with the 5 on top, and a + b at the bottom. The actual value of this expression will depend on the values of "a" and "b".
5........is this really a question? when b=5, then b=5
In algebra, the expression "b - 5" represents the subtraction of 5 from the variable b. This means you are taking away 5 units from the value of b. The result will depend on the specific value of b. For example, if b = 10, then b - 5 would equal 5.
a( 10 ) - b( 5 ) = 5 ?

b = 5, 10, 15, 20 or 25
Y = mx + b such as y = 3x + 5 the y-intercept (b) = 5
