I have no words. This thing always gets me. Even with the idea of rounding it doesn't validate any other number's identity. Why just these two?! O.o

Actually, all numbers have two notations.

1.5000... (or 1.5 as we'd normally write) is the same as 1.4999....

0.1000... is the same as 0.09999999 (this one is pretty easy to infer when one accepts that 0.999... is equal to 1, because 0.0999 is the same as 0.999.../10, and 0.1 is the same as 1/10, and because 0.999...=1, naturally 0.1 must be equal to 0.0999...)

So this works with every number then? The math problem that you showed at the beginning, works with any number? Btw, why didn't you add Maff to the poll?
