Explanation
Understanding the Problem We need to provide four examples for each of the following types of numbers: natural numbers, even numbers, odd numbers, prime numbers, composite numbers, and square numbers. Let's define each type of number and then list the examples.
Natural Numbers a) Natural Numbers: These are positive integers starting from 1. Examples: 1, 2, 3, 4.
Even Numbers b) Even Numbers: These are integers divisible by 2. Examples: 2, 4, 6, 8.
Odd Numbers c) Odd Numbers: These are integers not divisible by 2. Examples: 1, 3, 5, 7.
Prime Numbers d) Prime Numbers: These are numbers greater than 1 that have only two factors: 1 and themselves. Examples: 2, 3, 5, 7.
Composite Numbers e) Composite Numbers: These are numbers greater than 1 that have more than two factors (i.e., they are not prime). Examples: 4, 6, 8, 9.
Square Numbers f) Square Numbers: These are numbers that can be obtained by squaring an integer. Examples: 1, 4, 9, 16.
Final Answer Here are the examples:
a) Natural Numbers: 1, 2, 3, 4 b) Even Numbers: 2, 4, 6, 8 c) Odd Numbers: 1, 3, 5, 7 d) Prime Numbers: 2, 3, 5, 7 e) Composite Numbers: 4, 6, 8, 9 f) Square Numbers: 1, 4, 9, 16
Examples
Understanding different types of numbers is fundamental in many real-life applications. For example, when distributing tasks evenly among a group, you might use even and odd numbers to ensure fair allocation. Prime numbers are crucial in cryptography for secure data transmission. Composite numbers help in understanding factors and divisibility, useful in resource allocation and scheduling. Square numbers appear in geometry when calculating areas and volumes, essential in construction and design.
This answer provides examples for various types of numbers, including natural numbers, even numbers, odd numbers, prime numbers, composite numbers, and square numbers. Each category is defined clearly with examples that illustrate the concept. Understanding these types of numbers is foundational in mathematics and helps in various applications.
