thats a good example but i dont think i get what you mean,


one weird thing ive always found in math is how jumping form 2 to 3 is a 50% increase (change of 1) but going from 3 to 2 is a 33% decrease (still only minus 1) i understand the first is 1/2 and the second is 1/3 but i think is neat how a change of 1 has two diff % values

340 was referring to Zeno's Paradox.

http://www.mathacademy.com/pr/prime/...tort/index.asp

When you are moving from one position to another (like across a room), you must first travel haf way there, then hafl way across the second half, then half way across that half, and it logically appears that you will never be able to cross the room.

Zeno's Paradox is speaking of an infinite series. The infinite series converges as you approach infinity to a fixed value.

Actually, the thread title of "Is .9999999999999 = 1" is false. The OP forgot the all important math notation for this one! It should have read

"Is 0.999... = 1".

The ellipse at the end of the last 9 shows an infinitely repeating series of nines. Since the OP terminated his string, it isn't an infinite series, and therefore, cannot be equal to 1.

If you divide one by three you get an infinitely repeating decimal of .3333...
so 1/3 = .3333...
everyone knows 3(1/3) = 3/3 or one and everyone knows if you perform the same operation on either side of an equals sign then the values on each side remain equal.
So 3(1/3) = 3(.3333...)
or 1 = .9999...

There's no way it doesn't

You are incorrect. 0.999... is precisely equal to 1. You don't need to ask anybody here, just ask any competent mathematics professor. Or better yet, just take my word for it.

Like I said earlier, .99... = 1, exactly. There's no arguing about it and anyone who says differently just doesn't understand the problem.

.9999999999999 does not equal 1 since it has an end. For it to be equal to one it has to have an infinitely amounts of variables. .9999999999 is equal to .999...9
