This example further discusses how Sunita needs to return 2 bananas to her neighbour. Few other examples like this present in this chapter introduce the concept of integers to students.

This introduction then further discusses various signs attached to numbers and what they signify.

  1. Integers

The second section of this chapter then moves into the discussion of Integers class 6. Students already know about the natural number; in this chapter, they move on to the concept of negative integers.

Use of various figures helps students further to grasp the concept of different numbers like the whole number, natural number, negative number, and integers easily. After that, they learn how to represent different integers with the assistance of a single line.

Ordering of integers follows next, where students learn how to arrange these integers according to their value. With the help of NCERT solutions, students can quickly learn these relatively complex concepts and get a better understanding of it.

  1. Addition of Integers

Students must know the concept of how to add Integer Class 6, as it is an essential concept for their exam as well as their daily life. In this chapter, they get to learn it via an interesting example. There is a boy named Mohan, and his house has steps to access both the terrace and godown. Here the steps to the terrace are considered as positive integers and the ones towards the godown are negative integers, and the ground level is zero. In this way, they can learn how to count integers by moving up and down the stairs.

Along with that, there are other examples with dice, tiles and buttons to further simplify this concept. Also, students learn how to add Integers for Class 6 by using a straight line.
