odds and evens

      Odd and even numbers--the concept is useful in a few ways, if you learn it. Odd numbered addresses are usually on one side of the street, evens on the other, for instance. Parking regulations sometimes stipulate different rules for odd or even license plate numbers. All of the "even" numbers can be divided by two. If you wanted to share any even number of things between two people, the amounts would come out "even". Odd numbers cannot be divided by two. When you start with the first ten numbers, it's easy to see--
odd--1,3,5,7,9
even--2,4,6,8,10
Larger numbers are odd if they end in odd numbers. They are even if they end in even numbers, including zero(0).
So two people can evenly divide 778, 962 M&M's between them---but not 778,963.
