Question

What is the remainder when is divided by 13?

Answer 1

When what is divided by 13?

Answer 2

again, when what is divided by 13?

not enough information, and the only thing O can tell you is that the remainder is going to be less than 13. (any number from 12 to 1)

just like the remainder when the number is divided by n, is always n-1 and less.

(When the remainder os zero, it is not called the remainder.)
