Does anyone still have that link where several common mistakes regarding 0/0 and N/0 are dealt with? It was used several times like that link that critizises the 11/9 conspiracy theory.

candle, sqrt(-1)=1i. i means that the number is imaginary.

I get #DIV/0!

You all are dealing with some serious shit here. I hope your house is sturdy.

0/0 is indeterminate; it is NOT undefined. When a result is equivalent to 0/0, it means that you do not yet know its value, and more steps must be taken to determine it. The is in contrast to x/0, x != 0, which is undefined or infinite, depending on your application.

Without the frame of the calculus, dividing by zero has neither relevance nor meaning; you can write 0/0 on a piece of paper but it doesn't mean much. If you have any real-world situation where division is involved, situations where 0 is the divisor are resolved by using the calculus of limits.

Beyond saying 'indeterminate', as an applied mathematician I see little point in participating in a philosophy debate about 0/0's meaning.

You can't divide with a 0.

Guys, DON'T mess with this stuff! You could create a..



TIME PARADOX!

0/0 is UNDEFINED if both are real 0s. If they're infinitesimals then it is indeterminate.

You could of just tried it on a calculator, and still gotten the same answer you got here: "Error"

Thought about this for about 15 seconds and figured that the fact you are dividing 0 is ultimetly no different from any number because when you divide by 0 it can still go an infintecimle times into 0.

Any number divided by zero will be undefined, meaning that you cannot divide by zero at all.

4/2 = 2 because 2*2 = 4
14/7 = 2 because 2*7 = 14
60/5 = 12 because 12*5 = 60

0/5 = 0 because 0*5 = 0
5/0 = not defined because no number times 0 = 5
0/0 = not defined because any number times 0 = 0

That's why it is different. In fact that's the proof of why you cannot divide by 0.

So that means 0/0 equals 0?

Quote from RIVE

My Trigonometry teacher once said there was a way to divide zero by itself. I would guess it requires an equation using imaginary numbers. There's no way reals could be involved.

Just something to note, is that the imaginary number is the square root of -1.

And the square root of -1 isn't imaginary, it's a not real number.

SQRT(-1) or i is called the imaginary unit, a complex number is basically a real number plus a multiple of i.

Division by zero is undefined in the complex number system as well as our real number system.

Sorry candle, the square root of -1 is in fact imaginary: i.
Here is what the four basic terms of i equal, after this they all repeat.

• i = square root(-1) = i
  
• i² = square root(-1) × square root(-1) = -1
  
• i³ = square root(-1) × square root(-1) × square root(-1) = -i
  
• i to the 4th = square root(-1) × square root(-1) × square root(-1) × square root(-1) = 1
  

Let's take a power after 4 for an example of the repeating:
Equation: i to the 76th
Work: 76 ÷ 4 = 19
Answer/Simplest Form: i to the 76th = 1

i to the 77th = i = i
i to the 78th = i²= -1
i to the 79th = i³ = -i
And so on...

In my personal opinion, 0 is nothing. Nothing goes into nothing once. Therefore, the answer is 1.

Or in my other opinion, nothing cannot go into nothing because there is nothing for it to go into, so the answer is nothing.

0/0= link

Problem definitively solved.

yup. i believe in number 2

Sorry to say, but It really isn't a question of belief. It can be proven (and has been proven) that division by zero is meaningless, the answer isn't nothing, because there never was a question to ask.

Calculator says "Result of function is undefined."

My calculator seems to give me a LOOONNGG output of random numbers, before spitting out the reply: "Result = X". I have a really strange calculator.
