What are the essential topics for NVS TGT Mathematics Number Systems?

1. Natural Numbers and Whole Numbers:

• Understand the properties and differences between natural numbers and whole numbers.
• Explore concepts like the set of natural numbers $\mathbb{N}$ and whole numbers $\mathbb{W}$, including their operations and applications.

2. Integers:

• Study the set of integers $\mathbb{Z}$, which includes positive and negative numbers as well as zero.
• Familiarize yourself with operations on integers, such as addition, subtraction, multiplication, and division.
• Understand the concept of absolute value and its applications.

3. Rational Numbers:

• Study properties related to divisibility, such as prime numbers, composite numbers, and factors.

7. Number Patterns and Sequences:

• Explore different types of sequences and series, including arithmetic and geometric progressions.
• Understand the concepts of common differences and ratios in sequences.

8. Prime Numbers and Composite Numbers:

• Study prime numbers (numbers greater than 1 that have no positive divisors other than 1 and themselves) and composite numbers (numbers that have divisors other than 1 and themselves).
• Learn about prime factorization and its importance in number theory.

9. LCM and HCF:

• Understand the concepts of the Least Common Multiple (LCM) and Highest Common Factor (HCF).
• Learn methods to find LCM and HCF, including prime factorization and division methods.

10. Basic Set Theory:

• Familiarize yourself with the basics of set theory, including union, intersection, and difference of sets.
• Understand how sets relate to number systems.
