@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

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

Math of high school is mindfuck

Physics is not just mindfuck

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

**JustARandomPlayer has written:**

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.

**Apache uwu has written:**

What about this:

1/9 = 0.111~

8/9 = 0.888~

9/9 = 1

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

1 / randomnumber = randomshit

randomnumber * randomshit = 1 - 1 / infinity

1 = 1 - 1 / infinity

randomnumber * randomshit = 1 - 1 / infinity

1 = 1 - 1 / infinity

Ooh, exploitable.

Mixing 0.x and x/y in the same equation always leads to paranormal shit.

Let a=0.9~ , 10a=9.9~

10a-a=9a

a=1

10a-a=9a

**9a=9**a=1

isnt it actually 8.999°?

On the outside I may appear like an emotionless sarcastic piece of shit but just like an onion when you peel off more layers you find the exact same thing every single time and you start crying.

Lets say you know the answer now.

What is the point of this?

i know stupid question but it makes sense!!!

No, cause its 0.999999... and not 1,

Yes, cause when you round the number up youll get 1...

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.

I code, therefore I exist. | Visit my blog for Lua tips and other interesting info

**Wikipedia has written:**

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
