NCERT Solutions for Class 6 Maths Chapter 1 Knowing Our Numbers-

In the first chapter, Knowing Our Numbers we will deal with the number systems, some basic operations, etc. We have learned to work with numbers in our previous classes. We have added, subtracted, divided and multiplied them. In this chapter, we will move forward on interesting things like patterns in number sequences with a brief review and revision as well. In this chapter, there is a total of 19 questions in 3 exercises. The NCERT Solutions for Class 6 Maths Chapter 1 Knowing Our Numbers are created and prepared by our maths experts to clear students doubts regarding this chapter as well as these NCERT solutions help them in their preparation of class 6 CBSE final examination. The NCERT solutions for class 6 is the detailed explanation of each and every problem of NCERT textbook.

In NCERT Class 6 Maths Chapter 1 Knowing Our Numbers, we will learn Indian arrangement of numeration, the universal arrangement of numeration, learn large numbers up to 1 crore ( 10000000 ), estimation of large numbers and Roman numerals. We will also learn how to write and read these large numbers, comparing numbers for example which number is greatest and which number is the smallest among the given numbers. Using some digits we will make different numbers for example-suppose, we have four digits 8, 7, 5, 3. Using these digits we want to make different 4-digit numbers in such manner that no digit is repeated in them. Thus, 8753 is allowed, but 8853 is not. So the smallest and greatest numbers that we can make from these digits are 3578 and 8753. The other important topics that we are going to discuss in NCERT Class 6 Maths Chapter 1 Knowing Our Numbers are shifting digits introducing 10,000 and 1,00,000, revisiting place value and estimation to the nearest tens, hundreds and thousands.

Example: Population of City was 2,35,471 in the year 1991. In the year 2001, it was found to be increased by 72,958. What was the population of the city in 2001?

Solution: Population of the city in 2001 = Population of the city in 1991 + Increase in population

= 2,35,471 + 72,958

= 308429
