This question already has an answer here:
- Division by $0$ 17 answers
in arabic sites which is interested in maths , i find many topics like ,here is a proof that 0=2 .
and we answer that the proof is wrong as we can't divide by zero .
but i really wonder , why can't we divide by zero ?
i think the reason that mathematicians refused dividing by zero is that make us into a contradictions like $1=2=3=...$ and things like this , but those are facts about the physical world , why should mathematicians obey the outside world ?
i also have read a news in BBC about a new theorem which find special cases where we can divide by zero , but not details was mentioned i think , have any one had any idea about this ?
