What is integer with example 

An integer is a whole number that does not have a fraction or decimal part. It is a number that can be represented without using any fractions, decimals, or mixed numbers. 

Integers include positive numbers, negative numbers, and zero. Positive integers are numbers greater than zero, while negative integers are numbers less than zero. Zero is neither positive nor negative. 

Here are some examples of integers:

- 5

- -3

- 0

- 100

- -987

- 1,000,000

Integers can be used in many different mathematical operations, such as addition, subtraction, multiplication, and division. For example, if you add 2 and 3, you get 5, which is an integer. Similarly, if you subtract 3 from 10, you get 7, which is also an integer.

Integers are used in many different areas of mathematics, including algebra, geometry, and calculus. They are also used in everyday life, such as when counting objects or calculating distances.

It is important to understand the concept of integers because they are a fundamental part of mathematics. Many other mathematical concepts, such as fractions and decimals, are built on the foundation of integers.

In summary, an integer is a whole number that does not have a fraction or decimal part. It includes positive numbers, negative numbers, and zero, and is used in many different mathematical operations and areas of study.
