Other math problem

[Henkie36]

I just read another poll on a math problem (in the end, it was 14x0 = 0), but it did bring me back to another math problem I came up with a few months ago:
0/0.
Any random number devided by zero is infinite, and zero devided by any random number is zero. So what does that make this? Zero, or infinite?

(in the end, it was 14x0 = 0)

You sure you don't want to go back and check your math on that one?

There is a third possability. Any number divided by itself = 1 so does 0/0 = 1? This is my favorite so i'll go with 1.

Is that infinity or negative infinity?

A mathematician may like to discuss the idea for awhile. An engineer might tell you to shut up and that it doesn't matter.

It's an indeterminate form. There are numerous other indeterminate forms, check your local wiki.

Wrong.

a) The correct answer was 14 + 0 = 14.

b) Even IF you did the order operations wrong, by adding/subtracting before multiplication, you should have gotten 15*0.

0/0.
Any random number devided by zero is infinite, and zero devided by any random number is zero. So what does that make this? Zero, or infinite?

Anything divided by by 0 is undefined. ANYTHING. Including 0.

 

[Shadow flame master]

So 1/0 equals infinity and 0/1=0 and I need to find what 0/0 equals.

............

AAAHHHHHHHHHHH, fuck u math for hurting my brain AGAIN!!!!!!

 

[SckizoBoy]

You're all wrong, but now for a question that's actually interesting:

What is infinity - infinity?

Counter question: philosophically; physically; or mathematically?

 

[Dalek Caan]

It makes my brain hurt that's for dam sure. Probably zero.

How do you define your infinity? Is it describing a limit? Is it just an amount without end? How about answering this then: (infinity + 1) - infinity = ?

Though my fiancee (the engineer) over my shoulder says, "shut up, it doesn't matter". Meh. How can I argue with the logic of she who gives me lovins?

Mathematically.

Pity... I was hoping to wax lyrical there.

Oh well: still undefined, because infinity is not mathematically defined/definable with respect to real numbers. Involve complex analysis, though, and we devolve into the realm of Riemann surfaces, something I know an insufficient amount about to give you a proper answer.

 

[dyre]

I thought any number divided by zero = undefined, not infinity >_>

Dunno what 0/0 is though. Maybe 1, heh

In calculus you can solve this problem by applying a limit. So...

Lim x ---> 0 for f(x) = x/x is 1. That's how I would solve it. On a graph that point would appear as a whole on the line f(x) = 1 when x = 0.

 

[FinalHeart95]

well, I have no fucking clue, honestly. Let's say a number is x though:
0/0 = x So x would be whatever 0/0 is equal to.
0 = 0 * x
0 = 0

So, theoretically, x could be any number. So I don't know if it would be so much "infinity" as it would the set of real numbers (as in each number). That's just a somewhat educated guess though, so don't burn me if I'm not close.

EDIT: Forgot about limits. Then again, I didn't even take Calculus yet, that's next year for me.

YESSSS!!!!!!
although I disagreed with you on circumsision, absolutly right! anything divided by zero is ot infinity, it is undefinable, because one cannot evenly distribute simething amongst nothing, just aint possible, brilliant, absolutly brillian, i give you a golden star^^

So to condense my answer... the "answer" to the problem is 1. What you've stumbled upon is a good classic example of a calculus problem and it helps establish L'Hopital's Rule for solving problems with answers like f(a) = 0/∞ or ∞/∞ or 0/0 or ∞/0.
