Exploring the Mathematical Rule of Dividing by Zero

[Arkarian]

1. we know that the smaller the fraction we divide the bigger the outcome
1/0.5=2
1/025=4
i know that you are not supposed to divide by zero, because it messes up everything
but according to the first rule wouldn't it mean that 1/0=infinity
(i know it doesn't work if you reverse it, but please wait)
so the universe started from nothing/0, so if 0/0=infinity wouldn't that explain a lot, but how can you physically divide by zero?
if this theory stands, then wouldn't it mean that the universe can be destoyed and created by a black hole, since its 0.

Why should 0/0 equal what 1/0 might equal?

 

[topherfox]

0/100000000000000 = 0, 0/0.00000000000000001 = 0

The math part: the limit of 1/n as n approaches 0 is infinity, correct? However, this is very different than inccorectly stating that 1/0 = infinity.

As for the rest of the first post, I think that makes no sense whatsoever.

Summing zeros infinite times still results in 0. Summing 0.00(any number of zeros here)000001 infinite times results in infinity. A big difference.

Try solving for x:

1=x*0

You can't do it.

It's undefined.

You can't.

Numbers cannot be divided physically.

It's not a theory. It doesn't explain anything.

I used to be interested in this divided by zero stuff because after I took pre-calculus in the 11th grade, I had no math class in the 12th grade. But when I took Calculus I in college, I realize the mistake I made.

Take calculus.
