Question:
Is -2 an even number?



Replies:
Yes, Laura, -2 is an even number. An even number must be integrally divisible by 2. That means, when you divide it by 2 you get an integer: a whole number with no fractional part. -2 divided by 2 is -1 and since -1 is an integer, you can see that -2 fits the definition.

Eric Hagedorn


Yes, an even integer is an integer that is twice another integer. For example, 6, 0 and -2 are even, since 6 is twice 3, 0 is twice 0 and -2 is twice -1.

R. Paul Beem


Laura,

-2 is an even number. It is 2 times an integer, since -1 qualifies as an integer.

The definition of an "even" number is that the number is divisible by "2" without a remainder. Mathematicians would write an even number: E = (2xN). Then E is always divisible by "2". The definition applies to all integers, positive and negative, including 0. You can find more details at:
