Hello Bunuel.,

Can you tell me why you say "except 0 itself" ?

Sure.

An integer a is a multiple of an integer b (integer a is a divisible by an integer b) means that \frac{a}{b}=integer: so, as 0 divided by any integer (except zero itself) yields an integer then zero is a multiple of every integer (except zero itself).

Since 0/0 is undefined, then 0 is NOT a multiple of 0.

Hope it's clear.

I ask bunuel because I can vaguely remember the answer key for some mgmat problems listing multiples of 6 starting with 6 itself ie 6 12 18 which would suggest otherwise...
