Welcome to Chapter 2: Operations with Integers from your Class 7 Maths book, Ganita Prakash Part 2. If you want to truly master positive and negative numbers, Teachoo is the best place to learn.
This chapter builds on what you learned in Class 6. We will move beyond simple addition and subtraction to explore the rules for multiplying and dividing integers. We will use visual methods, like number lines and tokens, to understand why these rules work.
In this chapter, we will study:
A Quick Recap: We'll refresh our understanding of adding and subtracting integers.
Multiplication of Integers: This is the main focus. We will discover the rules for multiplying:

Two negative numbers (and why the answer is positive)
Division of Integers: We will learn the sign rules for division and see how it relates to multiplication.
Properties of Integers: We will explore important properties like the Commutative, Associative, and Distributive properties, which make calculations easier.
Understanding these rules is essential for all future maths, and the step-by-step explanations on Teachoo make these concepts simple and clear. We'll apply these rules to solve puzzles and real-world problems.
