Hi Aurino,

"There is no number which, multiplied by itself, gives a negative number as a result. Except, of course, for "i", which is defined as "a number which, multiplied by itself, gives minus 1 as a result"

Why can't we do the same thing for 1/0? There is no reason whatsoever. "

We can't do the same thing for 1/0 because any attempt to define it will introduce inconsistencies (see my post below). The definition of i does not introduce inconsistencies, so it is acceptable and very fruitful.

Warm regards,

Paul
