Even numberMarch 6, 2007
So, what’s an even number? Go ahead, try to explain it in your own words. I’ll wait.
When I was first asked this question I have to admit, I had no idea how to explain it. To think, we learn 2 + 2 = 4 at birth and some still have no clear understanding of what an even number is.
To get an understanding, let’s declare a variable k to be any randomly chosen integer and n be our mysterious even number.
n = 2k (our mysterious even number is equal to 2 multiplied by any randomly chosen integer).
This basically means that n is a multiple of 2. So, an even number is any number multiplied by 2.
Can anyone guess how to define an odd number?
