Is It Even or Odd?
To tell whether a number is even or odd, look at the number
in the ones place. That single number will tell you whether
the entire number is odd or even.
An even number ends in 0, 2, 4, 6, or 8.
An odd number ends in 1, 3, 5, 7, or 9.
Adding Even and Odd Numbers
even + even = even
4 + 2 = 6
even + odd = odd
4 + 3 = 7
odd + odd = even
5 + 3 = 8
Subtracting Even and Odd Numbers
even - even = even
4 - 2 = 2
even - odd = odd
4 - 3 = 1
odd - odd = even
5 - 3 = 2
Multiplying Even and Odd Numbers
even x even = even
4 x 2 = 8
even x odd = even
4 x 3 = 12
odd x odd = odd
5 x 3 = 15
Division, or The Fraction Problem
Division are Fractions are not even numbers or odd
numbers, because they are not whole numbers. They are
only parts of numbers, and can be written in different ways.
The terms “even number” and “odd number” are only used for
whole numbers and their opposites (additive inverses).
