Operations with Integers
Temperatures below zero, money owed and floors below ground level all need numbers less than zero. Chapter 1, Integers, of the NCERT Mathematics textbook for Class 7 extends whole numbers to positive and negative integers on the number line. You will add, subtract, multiply and divide integers, discover patterns in their signs, and use properties like closure, commutativity and distributivity to simplify calculations. Word problems from weather, banking and games give you practice in deciding which operation each situation needs.
