@Corvallis5: exactly.

One of my uncles showed me that long ago and solved it exactly like it your first post.

So I showed it to my math teacher ( Phd in math... he's a fucking genious i don't know why the hech he doesn't teach in a uni...). And he exmplained. When take 10a and remove a from it, there's a spot in infinity that actually stays. Basically a=0.99~, so 10a=9,9~, 10a's infinity is delayed

ohaz's demonstration quite nice too didn't expect it

On topic :No
Because 0.99999~=0.99999~ And 1=1


No. 0.99999~ ≈ 1.

Lets see what Google has to say: Clicky.

Wikipedia has written
In mathematics, the repeating decimal 0.999... (sometimes written with a different number of 9s before the final ellipsis, or as 0.9, 0.9 with dot over the 9, 0.(9)) denotes a real number that can be shown to be the number one. In other words, the symbols 0.999... and 1 represent the same number.

lol guys you absoluty don't know math
0,99999999999999999=0,(9)-that is how to write infinite 9 after ,

then when you study math you had a lesson about that:
0,(3)=3/9
0,(4)=4/9
0,(5)=5/9
....
0,(9)=9/9=================1(ONE)
so yes 0,99999999999999999999999999....99999=1
that is teh answer

just study math and you will see


You know, 9/9 is 9 divided by 9. Which equals 1 anyways.

10/10 equals 1.

x/x equals 1. Always.

Now see, you're doing it wrong. He says 0.999~ = 1. He's not right. 0.999~ ≈ 1, since you also can't say 5.412839781 = 5.4, it's 5.412839781 ≈ 5.4.

What about this:

IMG:https://upload.wikimedia.org/wikipedia/en/math/4/7/e/47e0d646891053c1f3b41fa8c81b6ebb.png


1/9 = 0.111~

8/9 = 0.888~

9/9 = 1

You shouldn't use divisions for that anyways.. Wikipedia is dumb.

0.9 repeating is equal to 1, it's a proven fact.

Its in the Off Topic section for a reason ya know.
Ironically your comment is off topic as well.

Btw this is true because thats what calculus uses and you can never go wrong with calculus... I don't even know calculus.

You're actually wrong. 0.9 repeating is 1. It IS one, 0.999.. = 1. No alternatives.

In the real-number system, 1 can be represented in two ways as a recurring decimal: as 1.000... and as 0.999... (q.v.).


They're not different numbers, just represented differently
