In Maths, integers are the numbers which can be positive, negative or zero, but cannot be a fraction. These numbers are used to perform various arithmetic operations, like addition, subtraction, multiplication and division. The examples of integers are, 1, 2, 5,8, -9, -12, etc. The symbol of integers is “Z“.

Integers

Integers are a set of whole numbers that include positive numbers, negative numbers, and zero. In Class 7, students learn about integers and their operations in mathematics. RD Sharma Solutions - Ex-1.1 Integers is a part of the curriculum that covers the basics of integers. Let's delve into the details of integers and the specific topics covered in this exercise.

Understanding Integers

- Integers are used to represent both the count and direction in mathematics.
- Positive integers are greater than zero, negative integers are less than zero, and zero is considered as an integer.
- Integers are represented on a number line, with positive integers to the right of zero and negative integers to the left.
