Uh. Who hit you with the idiot stick?

To all the people who say .999 repeating is NOT equal to one, can you tell me what number separates the two? Given any pair of nonequal real numbers, you can come up with a number between the two. This isn't a rule or anything, its just a characteristic of our number system. You can always break it down into smaller parts, .000015 is between .00001 and .00002 for example.

So because .999 repeating is NOT equal to one in your eyes, what number can you find that separates them?

I had to pause trolling just to say that this is probably the simplest and best explanation I have seen for this thing. And now, back to trolling the love line!

Say sally is 1 and Billy is 2 they both live forever at what point is sally .9999999999999% (repeating of course) of billys age if possible for sally to be .999999999999% of billy's age then it would prove that .9999999 does not equal 1

Thats nonsensical. You're trying to tie infinity to a real world concept. How many years would they live before they lived an infinite number of years? All you've done is say if y=x+1 and y=x, given enough time they'll never equal each other. No matter how large their ages get (y), they'll always differ by 1.

Well duh? You've said nothing about .999... repeating though.

Whats the point of trying to make convoluted and incorrect real-world proofs when mathematicians have so many elegant and simple ones?
