Definition of Counting Numbers

• Counting numbers, also known as positive integers, are whole numbers starting from 1 and going upwards indefinitely
• They are used to count and quantify objects, people, or things

Characteristics of Counting Numbers

• They are always positive (greater than zero)
• They have no decimal points or fractions
• They can be represented on a number line

Examples of Counting Numbers

• 1, 2, 3, 4, 5, ...
• These numbers can be used to count objects, such as:
  • The number of students in a classroom
  • The number of books on a shelf

• Counting numbers can be added and multiplied, but not divided or subtracted in the classical sense
• Examples:
  • 2 + 3 = 5
  • 4 × 5 = 20

Importance of Counting Numbers

• Counting numbers are the foundation of mathematics and are used in everyday life
• They are essential in various fields, such as science, engineering, economics, and finance
