Default want to Know why you can't divide with 0?

It suddenly struck me. Why is it that i can't divide with 0?
so i did a little research and came across this 2 part video that explains it very good. i thought i would share it with you guys, sense computer guys usually are interested in math as well.

I'm at work at the minute so can't watch the videos but how hard is it to understand?

If i have 10 sweets and 2 people to give them to i can give them 5 each.

If i have 10 sweets and nobody to give them to i can't do anything. . . . . therefore you can't divide by zero? Thats the way i've always seen it.

you say "If i have 10 sweets and nobody to give them to i can't do anything"
but why is that. 0 is a number like any other. why can't you mathematically not divide with 0.

why can't we just say that dividing with 0 will give you 0 or make it equal to "infinity".

the reason is that you can make a valid argument that 1/0 = "infinity" as well as a valid argument that says 1/0 = "negative infinity".

it's not hard to understand, i just find the video interesting, and that's why i wanted to share it.

The answer is there is no answer to your question. If this sounds like a nonanswer, let me explain. Multiplying any number by 0 yields 0, there is no number you can multiply by 0 to give you a nonzero answer. Finally dividing 0 by 0 gives you the entire real number line as an answer. That's why division by 0 is ruled out by mathematicians.

Aren't you glad you asked that question?

0 is not infinity. It's nothing. A place holder in math formuals.
This thread is totally random.

Can you divide 2 by nothing? Zero isn't a normal number. Like above said its a place holder among numbers. 7/0 means that you are dividing 7 by nothing. If you got 0 on your paycheck. You got nothing. Therefore dividing by 0 cannot give you a number, in fact if you graph that equation, you get a hole in your graph.

If you divide or multiply a number by zero: IT WILL STAY A ZERO.

If you multiply a number by nothing, you get nothing. However you cannot get anything from dividing by Zero. If you can figure it out I will be intrigued. Thanks.

I wish I had the time & energy to ponder such random things

No am not glad i started this thread, course i can see people are being jerks about it.
i'm well aware that it's not possible to divide with 0. i just find this video to be interesting. that's it.

If you say multiplying with 0 gives you 0 course there are no nothing to multiply with, then why can't you say that dividing with 0 gives you 0 course there are nothing to divide with?

did you even watch it?

There are arguments that suggest that dividing with 0 gives you infinity, but are counter suggested by the opposite negative infinity. did you watch the video? i find it a good video, so i wanted to share, and people bash me for it.
