OC 6.3 Q 25 mistake?

by alexac2 » Sat Jan 17, 2009 3:07 pm
If i and j are integers, is i+j an even integer?
1) i<10
2)i=j

Answer in the book is B. I think it should be E because what if i=0?

0 is an even number.
-2, -4, -6 are also even numbers.
So, B is correct.

0 is neither + or - but it is in fact EVEN
