Help me understand

Do you mean 8.999...999 or do you actually mean 9?

I mean what do you think 1*9 is?
Do you think it is 8.9999999999 or do you think it is 9?

I just want to make sure I'm solving the right problem, so I need to understand which numbers you mean

I have already provided them.

If you think these numbers are not the same, and I have asked you what is 1*9, why ask about other numbers.

If they were not the same number then what you are doing amounts to something like this exchange:

Me: "What is 1*9?"
You: "1 or 57?"
Me: "1"
You: "9 or 32?"

Notice how your questions are just pathetic attempts at stalling??

I have provided the numbers, 1 and 9.
What is the product of 1 and 9?
Can you answer that simple question, or must you continually avoid it because you know you are full of shit?

Well if you put it that way (and thank god you finally did), the product is 9. See how easy that was, why ask questions you know the answer to?

Didn't you claim that 9*1/9 doesn't equal 1??

0.999...999 != 1

Well if you put it that way (and thank god you finally did), the product is 9. See how easy that was, why ask questions you know the answer to?

Do you agree that multiple and division and inverse functions of each other?
That is if you have a*b=c, then c/b=a?

P.S. again, it was clear what the question was from the start.

I am asking them to step you through your problems.

it was clear what the question was from the start.

Well you were talking about the difference of 1 and 0.999...999 so the distinction was important.

I have to admit, its almost impossible to parse this globularist barble and I am an expert in mathematics. What exactly are you asking?!

I think he's saying he doesn't like my signature

0.999... != 0.999...999

You are arguing about a finite (but undefined) number of repeating 9s versus an infinite number of repeating 9s.

So wait, what happens if you add up 1 + (1+1) + (1+1+1) + (1+1+1+1) ...

What are you proposing should happen? And why do you feel it's relevant to the discussion?

I'm really not sure. I've heard arguments both ways, but if 1+ 0.999...999 = 2, we could end up with a negative number if we add up all those positives. We could expect no less out of globularist math.

Again, 0.999...999 is assuming a finite number of 9s, hence the end you have it. That is fundamentally different than 0.999..., which is a truly infinite series of 9s after the decimal point.

Either way, if you add them up indefinitely, you'll get a negative number.
All ways
0.9999 != 0.999999....999
0.999999....999 != 0.999999999999... !
0.999999999999... != 1.

You aren't adding the 9s.

Edit: hey no fair using the NSA toolkit to edit your post when I was already replying!

Ok, so let's call this the Grandi series: 1 - 1 + 1 - 1 + 1 - 1 + 1 - 1 + 1 - 1 ...

Now let's look at this series, and let's call it the Narcberry Series:
1 - 2 + 3 - 4 + 5 - 6 + 7 ...

And finally, the sum of what I said above, and let's call that the Neil Series, or the sum of all natural numbers:
1 + (1+1) + (1+1+1) + (1+1+1+1) ...
1 + 2 + 3 + 4 + 5 ...

So let's take two Narcberries, and we get:

 (1 - 2 + 3 - 4... )
+(0 + 1 - 2 + 3... )
----------------------------
1-1+1-1+1-1...

You are adding things together. That's not the same as using increasingly more digits beyond the decimal point.

You should call it the John Davis series and the Not Really realNarcberry series. I have nothing to do with the numbers you are adding together.

The boydster series would be 0.9 + 0.09 + 0.009 + 0.0009 + ...

And that series goes to 1 as the number of iterations goes to infinity.

Now the Grandi series, its 1-1+1-1+1-1+1...

Obviously, this adds up to 1/2 as it oscillates between 1 and 0. You can get deeper on this and consult Grandi, and his many discussers, but this is reasonable. Grandi is 1/2, the average of 1-1+1-1...

Two narcberries is cleary one Grandi from the previous post. So, 2n = 1b;  and then b = 1/2, so 2n =1/2 or n = 1/4. A narcberry is clearly 1/4.

So the Neil series is then (1+2+3...)

So, Neil minus a narcberry is then x= (1+2+3..)  - 1/4, or x = 4 times a Neil

Ok I'll change the names.

I'm on board with your current naming conventions.

Then we see clearly that:
(1 + 2 + 3 ..) - 1/4 = 4 (1 + 2 + 3 ..)

And then of course -1/12.

Now substitute in 1 = 0.999...9999. This leaves you with -1/12 - ( 0.0000...01)

Globe math. Just great. 1 + 2 + 3 + 4 + 5 = -1/12.

None of what you just went through has anything to do with 0.999... even though I'm sure it was fun for you to type out.

Pretty sure it did. You might want to review how you add up 0 + n/10 + n/100 + n/1000...

0.999...999 implies a finite series of 9s. See how it ends?

0.999... is an infinite series of 9s.

0.999...999 != 0.999...

One of those goes to one. The other falls short, but you failed to indicate exactly how short because you used poor notation.

Globe math. Just great. 1 + 2 + 3 + 4 + 5 = -1/12.

No. That equals 15, silly. Again, you are confusing a finite series with an infinite one.

No, I comprehended the notation and reacted accurately.
