Class 6 Mathematics is the foundation of higher grade maths, and RS Aggarwal is the most widely used textbook for practice, and it enriches the students' knowledge in mathematics. Students are advised to thoroughly practice through all the sums of this book because if their idea of basic mathematics is not strong, they may later face difficulties with high school advanced mathematics.
The first chapter in class 6th mainly talks about the number system, as the name suggests. The Number system is nothing but how you count things and their representation on paper! You'll learn about the whole numbers, natural numbers, the number line, and so many exciting things that you're going to use to understand the concepts taught in higher grades. For example, you must have heard about the number 1 Lakh. But have you ever wondered how many zeros there are in 1 lakh? Or, how do you know that a number is 1 lakh? What helps us determine to label a number as such even when the numbers seem so big? In this chapter, you will get to know about all these things and don't be afraid because it will be fun. You will also learn about the representation of numbers in the Indian style and the international system. For example, you will understand where to put a comma while writing a number and its significance in reading that number. This chapter will also teach you some ancient number systems, like the Roman numerals. You will be fascinated to see how the roman numbers are represented!
The chapter also elaborates on the concept of place value and face value and how these digits get their value in place value due to their position in the numbers. In case of any confusion, the Aakash institute provides RS Aggarwal Solutions for Class 6, which help you understand how to solve the problem given in the 1st chapter.
