"1" does not refer to anything. 1. You place a set of 40 different Pokemon Cards on a table in some order, labelled 1-40.
2. You divide the set by 1, equating 40 for Y.
3. Order is lost in simple division, treating all different cards as label 1.
4. Repeat step 1.
5. You divide the set by 2, equating 20 for X.
6. Order is implied for X has 20 specific cards out of 40.
7. Order is implied for Y.
8. 1 is not powerful enough a number.
2/40 can be a number of different cuts; at step 6 there are many possible sets of cards in X's control, and thus 2/40 = 20 is wrong; overly simple. You can try the same method with all labelled 1, and get the same result. There is an error at step 2.
40 cards are not the same as 40 1s. 1s seem to blend, per se, to make 2. No matter what, if you have 2 cards. That's card 1 and card 2, never a single card
So 1 + 1 does not equal 2, but rather (1 1), which can be said to be 2, but, following on from 2, is stupid, it's just a reference to (1 1), follow on from (1 1).
End.
