Is number '0' considered to be a multiple of other numbers?
for example, the following quesiton appeared in a kaplan
if x is a prime number, what is the value of x.
1. x< 15
2. (x-2) is a multiple of 5
In this case, i chose C cause 1 would give you 2,3,5,7,11,13 and 2 would give 7,17, 37 etc
choosing c would give 7. however, the kaplan
explanation also includes 2 as the prime number cause 2-2 is 0 and hence is a multiple.
Can someone please explain whether we consider 0 as multiples?
