Infinity + Infinity = ?

Re: Infinity + Infinity = ?

Ininity isn't assigned a value when you use it in equations. It's a direction not a value. I'd try to explain it in a way that makes sense but the simple fact is it doesn't make any real sense. It's just the way math works.

Nothing else can equal infinity, and therefore infinity plus infinity is some other measure entirely

Since infinity is a direction not a value you can't have multiples of infinity. Infinity is limitless increase. Adding something to limitless increase doesn't make a difference because it was already increasing. Taking something finite away doesn't make a difference because it will go right back to increasing.

Re: Infinity + Infinity = ?

The Infinite Hotel: You have a hotel with infinite rooms and every room is full. One more guest arrives at the hotel. How do you make room for them?

Move every guest up to the next room. (Guest in room n goes to room n+1, n is a positive integer.) Every guest still has a room and the first room is vacant. Since the first room is vacant, the new guest takes that room. There are still only infinite rooms and infinite guests.


Isn't infinity great?

Re: Infinity + Infinity = ?

How do you fill up every room if it has an infinite amount of rooms?

This whole topic is turning into a paradox.

Infinity + Infinity could be considered the question of Life, the Universe, and everything. Thus, the answer is 42, and we can conclude that infinity is 21.

Ok here's the debate that drives me nuts in math.

R/0 = undefined

No it isn't RETARDS

a positive real number divided by 0 is infinity!
Both graphing and story problem logic can prove it.

If I have 5 apples and I'm making groups of 0 apples, how many groups can I make? Infinity, I can keep making groups of apples and I'm never gunna run out! Here's yours and yours and yours....

Also graphing:



for y=1/x, when x is 0 y is infinity, actually most computer graphing calculators tell you this.

Plus if more people went with this we could stop giving all the exclusions like x=R but not 3.

Got this from Wikipedia.
Undefined Operations:
1 to the power of +/- infinity
0 x +/- infinity
infinity - infinity
+/- infinity / +/- infinity
+/- infinity to the power 0

Red, you were close.

Infinity + Infinity = 16

Re: Infinity + Infinity = ?

with the deduction on the previous page these can all be solved.

1 to the power of +/- infinity~~~

it's 1, can't be negative one because -inf has 2 as a common factor.



0 x +/- infinity~~~

Real Number



infinity - infinity~~~

0



+/- infinity / +/- infinity~~~

1



+/- infinity to the power 0~~~

1, because if I have 4^0 it's 1 and 3^0 its 1, now inf is composed of every factor infinitely, and in first problem we said R^inf = 1, therefore inf to the power of 0 is = to 1*1*1*1*1... which is 1.

Re: Infinity + Infinity = ?

Infinity + 1 = an infinate amount over 1.

Infinity - 1 = infinity starting at -1.

Infinity / Infinity = 1, because Infinity is an infinate amount of numbers divided by themselves, and any number divided by itself is 1.

Infinity / 0 = not possible except when when it's 0 in infinity, which would make the answer 0.

Infinity + Infinity = Something you couldn't possibly fathom.

Think of it this way. Dividing a pie in half is cutting it into two pieces, thirds three pieces, and so on. Now try to cut a pie into zero pieces. Don't get rid of the pie or eat it, just cut it so that there are zero pieces. If you can do that then you can say division by zero is defined.

Also the graph never actually touches the y axis (x=0) or the x-axis (y=0). NEVER! Many graphic calculators will tell you the answer is infinity but better ones will give you an undefined error.

Hey! I'm not... Well yeah okay but I'm not a... Shut up, you!

You can't cut a pie into zero pieces.

Interesting that the better calculators are the ones that give you an undefined error.

You have it backwards, since you cannot define a number that is continually growing, "Infinitiy" is not a number--It is a vague mathematical verbage for a very large or small number that has no significance.

When they ask 2/0=x on a test, they are looking for the Number for the answer, not the Concept of WHY the number is undefined (Infinite Division)

What is 2/0? Undefined
Why is 2/0 Undefined? Because it can be divided infinite times.

Thus, you are answering the Why, not the What.

I would not count 2/0=Infinity correct on a test I was grading, and I doubt any professor would.
