2. 1 Introduction to Number Systems Number systems are ways to represent and understand numbers easily. They are used in daily life, mathematics, and computer science. Learning about number systems helps us understand different ways to express numbers.

3. 2 Types of Number Systems The main types are natural numbers, whole numbers, integers, rational, and irrational numbers. Each type has different properties and uses. Understanding these helps in solving various mathematical problems.

4. 3 Natural Numbers Natural numbers are counting numbers starting from 1, 2, 3, and so on. They are used for counting objects and simple calculations. Zero is not included in natural numbers.

5. 4 Whole Numbers Whole numbers include all natural numbers along with zero. They are used in situations where nothing or zero items are involved. Whole numbers are non-negative integers.

6. 5 Integers Integers include all whole numbers and their negative counterparts. They are used to represent temperatures, debts, and elevations. Zero is an integer, and so are positive and negative numbers.

7. 6 Rational Numbers Rational numbers are numbers that can be expressed as a fraction of two integers. Examples include 1/2, -3/4, and 5. They can be terminating or repeating decimals.

8. 7 Irrational Numbers Irrational numbers cannot be written as simple fractions. Examples include √2, π, and e. Their decimal expansion is non-terminating and non-repeating.

9. 8 Number Line A number line is a visual representation of numbers in order. It helps in understanding the size and position of numbers. Both positive and negative numbers are shown on the number line.

10. 9 Importance of Number Systems Number systems are fundamental for solving mathematical problems. They are essential in computer programming and digital devices. Learning different number systems builds a strong mathematical foundation.
