It's not.

because it isnt that way. you cant treat infinity as a variable, you treat it is a limit some other variable is approaching.

>>5902811
When will you people learn, infinity is an idea, not a number.

>>5902874
When will high school retards like you learn to shut the fuck up when you have no fucking idea what you're talking about?

>>5902879
dear diary, today anon was a bro and taught me that infinity is a number, its right there after

240503030

and before

anons a cool guy, hes my best friend.

Why do you keep perpetuating this retarded troll joke? Do you think you're funny or something? You're not. You're just making yourself look retarded.

This is probably more than you need.

Fuck off, retard.

>>5902920
What is your fucking problem, you piece of shit? Do you think Cauchy, Euler and Riemann were all wrong and their theorems are worthless because a 14 year old imbecile just figured out that HURRR DURRRR INFNTY NOT A NUMBR LOLOLOLL? Yeah, right, the Riemann sphere doesn't exist because infinity is not a number. Möbius transformations are worthless garbage, because infinity is not a number. Projective geometry? Has been wrong for hundreds of years and just today a teenager on 4chan found out why: Because infinity is not a number. Who the fuck shat in your brain?

>>5902935

idk why you're so mad about being wrong

http://en.wikipedia.org/wiki/Riemann_sphere

infinity used in the sphere isn't the same infinity we talk about with limits and w/e.

the only reason it's used as a number is because it was defined as a number

when most people talk about infinity, they're talking about something else.

This is all probably straining on your feeble mind, so please leave /sci while you think about it

>why is infinity divided by infinity equal to one???
It's not

There are different types of infinity, some growing at faster rates than others. Although all infinities will grow forever and are divergent, a faster infinity divided by a slower infinity, or vice versa, will not result in zero.

>we talk about with limits

So we can't do arithmetics in the extended real number line?

http://en.wikipedia.org/wiki/Extended_reals#Arithmetic_operations

This wikipedia article is wrong? All the operations are not defined because hurrrrrrrrrrrrr infinity isnt le number xDDDD???? You better go there and correct the article. And while you're at it, you might want to change all analysis textbooks because they're obviously propagating falsehoods. Fucking dumbass. Remove your subhuman stupidity from our gene pool.

>>5902811
because % %% is + & the 'half' or 'middle' is infinite

capeesh?

>>5902920
>>5902944
Cardinal arithmetic? Hyperreals? One-point or two-point compactifications of the reals? ALL BULLSHIT /B/CAUZ INFINTY IS NOT LE NUMBER XDDDDDD, AMIRITE GUISE?

Why haven't you won a fields medal yet with your superior intelligence?

There you head it, guys. All math debunked by a middle schooler. Why hasn't anyone thought of this before? How the hell did mathematicians treat infinity as a number for hundreds of years? lol math must be full of idiots xD

>>5902971
>How the hell did mathematicians treat infinity as a number for hundreds of years? lol math must be full of idiots xD
Because they think idea's numbers & concepts are all the same thing
Any other questions need answering?
Just some Psychoanylilyzation

never go full retard

"Infinite" has a well-defined meaning if used without context; "infinity" does not and could refer to any number of things.

OH MY GOD How did we ever dare to think of numbers as concepts? Of course all numbers are objects in the real world. We can observe them and study their behaviour. Just yesterday I was allowd to witness the copulation of a 2-3i and a square root of pi/7. A very rare event in nature.

Today I learned that numbers are not concepts.

>>5903005
You didn't make a clever there.
You just showed you have trouble with the differences in concepts, abstractions, and other non-concrete terms.

I'd explain, but you just showed us you won't understand.

Sure is samefag in here.

Infinity divided by infinity is not 1 because you can't treat it as a standard fucking number.

Pic very related.
