My doubt is - In gre, when we list the multiples of a number n (lets say n = 10), do we include 0 as a multiple?
Yup, 0 is a multiple of all numbers! It is there in one of Greg’s videos

According to my understanding,
If we list multiples of a number, we need to include 0 (as a number has infinite multiples as it can be multiplied with any whole number and we have infinite whole numbers.)
However if mentioned in question we want non-zero multiples, then we need not include 0.
