An even number is a whole number that is divisible by 2 without leaving a remainder. In other words, if a number can be divided by 2 and the result is a whole number, then it is an even number.
1. Even numbers always end in 0, 2, 4, 6, or 8.
2. The sum of two even numbers is always an even number.
3. The product of two even numbers is always an even number.
To identify if a number is even, you can use the division test. If the number is divisible by 2 without leaving a remainder, then it is even. Another way is to look at the last digit of the number, if it is 0, 2, 4, 6, or 8, then the number is even.
