Even number
From Wikipedia, the free encyclopedia
An even number is an integer which is a multiple of two. If it is divided by two the result is another integer. Zero is an even number because zero multipied by two is zero. The next four bigger even numbers are two, four, six, and eight. You can tell if a decimal number is an even number if the last digit is an even number.
