Yes it is, just not a real number.   

This video (while it's not the main subject of it) explains all about infinity, which is also a source to my earlier statement: http://www.scratch.mit.edu/ext/youtube/?v=TINfzxSnnIE She never refers to the 9s in 9.999... as anything other than an "infinite number of 9s."

Yes, as in the digit, not the number 9.

Yes, but it's an infinite amount of them.

Yes, but that doesn't mean it equals infinity. There are just infinity of them.

Ok, I see your point. But again, what evidence do you have that infinity - infinity doesn't equal 0?

I love that video.  I've watched it.

However, it doesn't mean it's infinity.  0.3333.... =/= infinity

Yes, I see that. But it does mean that it's possible to minus an infinite amount of something by an infinite amount of something, and I fail to see how that concept shouldn't work with infinity itself.

Yes it is, just not a real number. 

But not an imaginary number either, because there's no i.  So, they should have a separate category for infinity and numbers involving infinity.

There are plenty more categories of numbers than just real and imaginary.    If I remember correctly from that video, infinity is a super real number.

Surreal.  Or hyperreal.  But if it's a number, then my conjecture is correct.  xP

if its either of those, you still cant compare it to an integer.
that's still not an integer solution, either if it is one of those.

Most people.  Especially colleges.  Anyways, infinity is definitely greater than 2.

are you actually going to respond to my argument or what

I said:  infinity is greater than 2.  Can you defy that?

Would you mind?  I agree with lalala3.  Don't want to type the same thing in a different format ( ) but the source is common sense.

Wait, wait, wait. Hold up.
Let's set x to infinity. So x is constantly growing larger at the same rate, right?
So why doesn't x - x = 0?
If infinity is singular, then every time the number grows, the variables should be equal.
And a number subtracted from itself equals zero.
Quota era demonstrata?

Some infinities are larger than others.
And infinity is, for lack of a better word, infinitely large, so therefore, it's going to be infinity still.
Quite Easily Demonstrated.  xD  That's what my math teacher told us it means jokingly.

1. No.
2. Either irrelevant or fallacy of equivocation.
3. Hehe

I think by some infinities are larger than others he's referring to the infinite number of decimals between integers and the number of integers. Those are still the same infinity, though. Infinity isn't a number, and doesn't behave like normal numbers. The amount of rational numbers between two integers and the amount of real numbers is the same.

I was considering infinity to be a sequence of ever-growing whole numbers (1, 2, 3, 4...)
although saying the infinity - infinity was different numbers is silly because you gave no distinction between them.
And 3.3_ - ∞ =/= ∞ anyway.
