You can't subtract .9999999.... logically. That assumes infinity has an end.
9.999999 -.999999 = 8.999991

1/3 = 0.3333333..... 2/3 = 0.6666666..... 3/3 = 0.9999999..... It's a lie, 1/3 does not = 0.33333....1/3 equals 60 degrees.

Since when is etc a number?
Do me a favor, can you write out the whole number for me, so we can do the equation? Edited by riVeRraT, : No reason given.

You can't subtract a recurring .9 because if you went to write it out, you would never reach the end. So you would never finish writing the equation, can't be done logically.

But what is to prevent us from subtracting all digits at once? There is nothing "all" about infinity. I do not agree with this:Fraction proof The standard method used to convert the fraction 13 to decimal form is long division, and the well-known result is 0.3333 . , with the digit 3 repeating. Multiplication of 3 times 3 produces 9 in each digit, so 3 0.3333 . equals 0.9999 . ; but 3 13 equals 1, so it must be the case that 0.9999 . = 1. I also do not neccesarly think infinity actually can exist either. It's only a thought, not a number. How can you subtract 0.9999... from 9.9999 digit by digit if the digits have no end? You will never solve the equation. The numbers have no end, therefor the equation has no end. There is no acurate way to express 1/3 of 10 in decimals in a number system based on 10. So if .9999...=1 then infinity does not exist. This only happens if the number is actually representing something. Is it impossible for a number to not represent something?

Sorry, that math is beyond me.
It's not like I don't get why .9999...= 1, I do. I just don't agree with the math. I can prove that 0.9999... = 1 also 1/3 of a circle with the circumference of 1 yard = 0.333333.... 1 yard = 0.914400 meters 1/3 of 0.914400 = 0.3048 0.3048 meters = 0.33333....yards. So 0.3333... is a whole number. Now do it in reverse, and you will find that 0.99999=1 The real problem lies in that we do not have an accurate way of expressing 1/3 in decimals. If 0.9999... is representing something in the universe, and our universe is infinate, then the number can go on, and on without ever being 1. If the universe is finate, then 0.9999... will eventually come to an end, then infinity only exists in our subjective minds.That means that 0.9999.... = God. Edited by riVeRraT, : clarity, if there is such a thing

We CAN see that the number will be 0.999.. less. What's the problem? The problem is that you are using a finite symbol to represent infinity. Try writing it out. If you did, you'd find that 0.9999... does in fact equal 1, 1 dead person. You'd also find out the infinity does not exist for us in the physical sense.

Can you prove that 0.9999... even exists?

Not sure, you are trying to solve for n?

btw the colour blue does not exsist its just a label for a wavelenght of light Yes blue exists. We have had this discussion before. Blue is not just a wavelength of light. It is how our brains interpret that wave length when viewed through our eyes. Which is a separate thing from the actual wave length of blue light.

But that's what I am saying, 0.9999... is not a number.

Here you can read up on some of our discussions about sound and light. I think we covered most of it there.

We can only approximate it.
I use pi all the time, and 3.14 gets me close enough.

We need not concern ourselves with the infinity aspect of the values to the right of the decimal since all we need to know is that they are equal to one another Says who? Since you can't get the end of the number, then you never really know if it is equal or not. It is not an absolute. Can you prove infinity exists?
By some[citation needed], infinity is considered to be not a number but a concept of increase beyond bounds. Infinity - Wikipedia I am in over my head here, and the conversation will get deeper than my knowledge. I do pocess the capability to figure this stuff out. I hope to go to college one day soon. I have been too busy with the school of life. But the way I see it, and this is from ignorance, it's not that 10 can't be divided by 3, it's that it can't be expressed correctly with our number system. I started reading about other number systems that can express it correctly, but I just don't have the time. Saying 0.9999... = 1 means that infinity resolves to something in this case. But infinity cannot resolve, it is suppose to go on and on. So I find there is a problem.
