Understanding Odd and Even Numbers
Odd and even numbers are fundamental classifications in mathematics.
Definition of Even Numbers
Even numbers are integers that can be divided by two without leaving a remainder. They can be expressed in the form of 2n, where n is an integer. Some examples of even numbers include:
- 0
- 2
- 4
- 6
- 8
- 10
Definition of Odd Numbers
Odd numbers, on the other hand, are integers that cannot be evenly divided by two. They can be represented in the form of 2n + 1, where n is an integer. Examples of odd numbers include:
- 1
- 3
- 5
- 7
- 9
- 11
