I said indeterminate.

Indeterminate means you cannot tell the answer, because of infinity, meaning forever.

Welcome to the forum. Look at this.

There is no single answer to this, as infinity is not a number in the strictest sense.

Infinity is a "limit". It is something you can get closer and closer to, but you never

quite reach it. What matters is how fast you approach the first infinity (call it

infinity01) versus how fast you approach the second infinity (call it infinity02). If

you approach both at exactly the same speed, always the same distance from each, then

infinity01-infinity02=0. If you are always a little closer to infinity01, then

infinity01-infinity02 is a positive number. If you move toward infinity01 twice as

fast as how you approach infinity02, then infinity01-infinity02=infinity. The behavior

of limits is not quite the same as the behavior of numbers.

I agree with some of this and some I am not sure of. Lets wait for some of the other posters who are way more rigorous to settle the question.

]]>Infinity - Infinity = ???

Now when you first look at this you might think it equals zero. But look at it like this:

If you have infinity marbles and you give infinity (As in all of them) to someone else then infinity - infinity = nothing.

But if you have infinity marble numbered 1, 2, 3 etc. and gave every second marble to someone then infinity - infinity = infinity

BUT if you give someone else all the marbles numbered 3 or above (Which is infinity marbles) then infinity - infinity = 2.

But the question is in all these examples are you really giving infinity marbles away and do you still have infinity (Or whatever) left???

What do you guys think anyway?:)
