Can you tell me why even numbers are even and odd numbers are odd?

An even number is a number that can be divided into two equal groups. An odd number is a number that cannot be divided into two equal groups. Even numbers end in 2, 4, 6, 8 and 0 regardless of how many digits they have (we know the number 5,917,624 is even because it ends in a 4!). Odd numbers end in 1, 3, 5, 7, 9.

How do you divide even numbers with odd numbers?

An odd number will always have a remainder of 1 when dividing by 2. So breaking up the number in this way helps you divide the number quickly, since an even number will have no remainder when dividing by 2. To break up the number into an even number +1, subtract 1 from the number. Divide the even number by 2.
