Is zero an even number?
by iRabbit » Wed Mar 02, 2016 9:58 pm
I'm just wondering if zero is considered an even number. Let's put this qn in the context of a P3 problem sum that asked for the smallest single digit, nonnegative, even number. Should the answer be 0 or 2? Thanks.

Lol. So chim. Is zero a prime number? Or a real number?

I googled that page too but wondered if P3s are supposed to understand that. It's like in physics first we learned that light travels in straight lines then a few levels later, we were taught light travels in waves.
If zero is considered as even, then at least one assessment book is wrong.
Thanks for sharing, pirate.

My son said that zero is even, though I don't 100% believe him. But for the rest of your questions, think you better asked those NUSH students.

Zero is a digit, even though it represents nothingness or no value. You can get zero from 55.
Zero is neither positive nor negative. It separates the positives and negatives. It is unsigned.
Nonnegative refers to all the numbers that are not negative. So this refers to the positive numbers and zero.
Zero is considered an even number. There are a lot of explanations in https://www.quora.com/Iszeroevenorodd.
So for the "the smallest single digit, nonnegative, even number", I'll go for zero.

No need. Just ask prof Google.
Zero is not prime because it is less than 1. Prime numbers have to be bigger than 1, which means 1 itself is not prime.
Zero is an integer, so it is a real number.
In the end, it is really about who defines the concepts of even, odd, prime and real numbers

Okay with a nick like yours, I can't argue with you.
I'll tell my friend's kid to take zero as even. He was doing a question that asked for the smallest, even number that is positive.
