comment Not clear on what we mean with numbers with infinite digits
But 1/2=3/6=0.5 While 6/3=2 vs 6*(1/3) = 1.999999.. =~ 2

Yes but 6/3=2 not 1.9998. So how come with 2 different ways we get exactly 2 and we approach 2?

...means the limit of the sequence of rational numbers: I am ashamed to say I don't understand this part TBH

But then why doesn't 1.99999999... equal to 1.88888888.... and then 2 equals 1.8888888888 for 1.8888.... and 1.777777....>

What do you mean by the 1.99999999999...? That 2 = 1.99999999.....?

@GitGud:I was trying to find an intuitive explanation of this.Perhaps the number with infinite digits has properties I am not aware of

comment Refresh summation formulas
The result of your answer is O(N^4) while three nested loops are always O(N^3). Something is wrong here. Am I messing up something in my OP?

@user18921: So bijection creates an ordering?So a bijection is a "random" ordering of a set?

comment Fundamental confusion on set theory and permutations
I am sorry for the question but I am not sure what you mean by a set having a particular structure.I am thinking of a set in the terms of just being a container where an element either is or is not part of the set and order is irrelevant.Can you please explain this one?
