Comment on Even and Odd Integers

0 is neither even nor odd.

Zero is even.
An integer is even if that integer is divisible by 2. An integer, n, is divisible by 2 if n = 2k, where k is an integer.

So, for example, 10 is even because 10 = (2)(5), and 5 is an integer.
Likewise, -22 is even because -22 = (2)(-11), and -11 is an integer.
Similarly, 0 is even because 0 = (2)(0), and 0 is an integer.

zero is neither positive nor negative

That's true

appears this lesson (and the reinforcement ques associated with the video) are arguably one of the most important ones in your module in preparation for the test. do you have a top 10 must know inside and out videos (from GMATPrepNow), based on your knowledge of where the 37 quant questions might come from

I don't have such a list. However, the number of practice questions related to each topic is a good indication of the importance of that topic.
