Key concepts include natural numbers, whole numbers, integers, rational numbers, and irrational numbers, along with their representations on the number line and in decimal form (terminating and non-terminating). The chapter also covers operations on real numbers and their properties. 👨‍🏫 Key topics covered in the number system for class 9: 📚 Natural Numbers (N): These are the counting numbers starting from 1 (1, 2, 3, ...). 📚 Whole Numbers (W): Whole numbers include natural numbers and zero (0, 1, 2, 3, ...). 📚 Integers (Z): Integers encompass both positive and negative whole numbers, including zero (-3, -2, -1, 0, 1, 2, 3, ...). 📚 Rational Numbers (Q): These can be expressed as a fraction p/q, where p and q are integers and q is not zero (e.g., 1/2, -3/4, 5, -7, 0). 📚Real Numbers (R): This set includes all rational and irrational numbers, which can be plotted on a number line. 📚 Irrational Numbers: Numbers that cannot be expressed as a simple fraction (e.g., √2, π). 📚 Decimal Representation: Understanding terminating (e.g., 1.5) and non-terminating decimals (e.g., 0.333...), including recurring (repeating) and non-recurring decimals. 📚 Operations on Real Numbers: Addition, subtraction, multiplication, and division of real numbers, including those involving square roots. 📚 Properties of Real Numbers: Closure, commutative, associative, distributive properties, etc. 📚 Euclid's Division Lemma: A fundamental concept used in finding the Highest Common Factor (HCF) of two numbers. 📚 Fundamental Theorem of Arithmetic: Every composite number can be uniquely expressed as a product of primes.
