If a DS problem speaks about "positive integers", can zero be considered one?
1. Zero is neither negative nor positive.
2. Zero is an even integer.
An even number is an
integer that is "evenly divisible" by 2, i.e., divisible by 2 without a remainder and as zero is evenly divisible by 2 then it must be even (in fact zero is divisible by every integer except zero itself).

P.S. Please post math related questions in main math forum here:
gmat-quantitative-section-7/?fl=menuThank you very much Bunuel. So for the GMAT zero is an integer?
Yes. Integers are defined as: all negative natural numbers \(\{...,-4, -3, -2, -1\}\),
zero \(\{0\}\), and positive natural numbers \(\{1, 2, 3, 4, ...\}\).
