# What is an Integer?

An integer is a type of number that can be positive, negative, or zero. It doesn’t have any fractions or decimals. Imagine counting whole apples, whole oranges, or whole bananas – you can’t have half an integer, just like you can’t have half an apple if you’re counting whole apples.

#### Why are Integers Important?

Integers are important because they help us do math in everyday life. Here’s why they matter:

1. Counting: Integers help us count things in whole numbers, like how many books you have or how many friends are coming to your party.
2. Math Operations: Integers are used in all kinds of math operations like addition, subtraction, multiplication, and division.
3. Representing Values: Integers are used to represent different values in math, such as temperatures, elevations, and money.

#### How Do Integers Work?

Integers include positive numbers, negative numbers, and zero. Here’s a simple way to understand them:

1. Positive Integers: These are numbers greater than zero, like 1, 2, 3, and so on. They are used to count things you have, like 5 apples or 10 stickers.
2. Negative Integers: These are numbers less than zero, like -1, -2, -3, and so on. They are used to represent things you owe or temperatures below zero, like -5 degrees.
3. Zero: Zero is an integer that represents nothing or no value. It’s like having zero cookies in the cookie jar.

#### Fun Fact

Integers are used in many games to keep score. For example, in sports, scores are always whole numbers, never fractions or decimals!
