An even number is a whole number that is exactly divisible by 2. In other words, when an even number is divided by 2, the remainder is 0.

Some examples of even numbers are 2, 4, 6, 8, 10, 12, 14, 16, and so on. These numbers can be divided by 2 without leaving a remainder.

- When you add two even numbers, the result is always an even number.
- When you multiply an even number by any other whole number, the result is always an even number.
- The sum of an even number and an odd number is always an odd number.

To identify if a number is even, you can simply check if it is divisible by 2. If the remainder is 0, then the number is even.

- Determine whether the following numbers are even: 14, 25, 36, 41, 50.
- Find the sum of the even numbers between 1 and 10.
- If 2x + 4 = 16, find the value of x.

- 14 and 36 are even numbers.
- The sum of the even numbers between 1 and 10 is 30 (2 + 4 + 6 + 8 + 10 = 30).
- x = 6.

Understanding even numbers is essential in mathematics, as it forms the basis for various concepts such as divisibility, algebraic expressions, and number patterns. Practicing with even numbers can help build a solid foundation in mathematics.
