Even and Odd Numbers - Math for Kids
We say that a number is even when grouping its elements two by two, there are none left over. We say that a number is odd when grouping its elements two by two, there is always an extra one. And how is it possible to know if a very large number is even or odd? In every even number, the unit digit is always 0, 2, 4, 6, and 8. While in odd numbers, the unit digit is always 1, 3, 5, 7, or 9.
