Odd/Even Numbers
In mathematics, numbers can be classified as either odd or even.
Even Numbers
An even number is a number that is exactly divisible by 2. In other words, when an even number is divided by 2, the remainder is 0. For example, 2, 4, 6, 8, and 10 are all even numbers.
Odd Numbers
An odd number is a number that is not exactly divisible by 2. When an odd number is divided by 2, the remainder is always 1. For example, 1, 3, 5, 7, and 9 are all odd numbers.
Determining Odd/Even Numbers
To determine if a number is odd or even, you can simply divide the number by 2. If the remainder is 0, the number is even; if the remainder is 1, the number is odd.
Properties of Odd/Even Numbers
Even numbers can be represented as 2n, where n is an integer.
Odd numbers can be represented as 2n + 1, where n is an integer.
