so from Apocalypse post

What about 0/0? Suppose we say 0/0 = c where c is some real number. Will it check? 0(c) =0. Certainly it checks. What value should we give c? Why not 1? 0/0=1 since 0(1) = 0. But 52 would work equally well. 0/0 = 52 since 0(52) = 0. Since any number will check, 0/0 lacks a "unique" answer. Again mathematicians ruled out 0/0 as a permissible operation because of this lack of uniqueness.

we can say that 0/0 is any numbers in the world (since it satisy the that rule)........... so I think the answer of Kezil post is undefined (0/0) because if the answer is all numbers it's better to say undefined.. isn't it make life easier ???
