    is 0 a multiple of any one number?

    Hi fellas. I am preparing for the GRE. In the Barron's book, an example is:

    'A number is "terrific" if it is a multiple of 2 or 3. How many terrific numbers are there between -11 and 11?'

    Answer: There are 15 "terrific" numbers: 2, 3, 4, 6, 8, 9, 10, their opposites, and 0.

    So my conclusion is that 0 must be a multiple of any one number? Is that so?

    It is a multiple of every number:

    0=2 \times 0
