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

 11-12-2012, 10:24 AM #1 Fully Optimized     Join Date: Feb 2011 Location: Denmark Posts: 4,026 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. __________________ __________________ He who has never failed has never attempted anything worth succeeding at.

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? __________________

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 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.

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.
