# What is an Integer?

Have you ever counted your toys or measured something in whole numbers? Those whole numbers are called integers! An integer is a number that can be positive, negative, or zero, but it doesn’t have any fractions or decimals.

Here’s how it works:

1. Whole Numbers: Integers include all the whole numbers. These are numbers like 1, 2, 3, and so on. For example, if you have 3 apples, the number 3 is an integer.
2. Negative Numbers: Integers also include negative numbers. These are numbers like -1, -2, -3, and so on. If you owe someone 2 dollars, you can think of it as -2 dollars.
3. Zero: Zero is also an integer. It’s the number that represents having nothing at all. For example, if you have zero candies, you don’t have any candies.
4. Number Line: You can see integers on a number line. On this line, positive numbers go to the right, negative numbers go to the left, and zero is in the middle.pythonCopy code`... -3, -2, -1, 0, 1, 2, 3 ...`
5. No Fractions or Decimals: Integers are always whole numbers. This means they don’t include fractions like 1/2 or decimals like 3.14.
6. Everyday Use: We use integers every day! When you count objects, measure distances, or keep score in a game, you’re using integers.

Understanding integers helps us do math more easily and accurately. They are the building blocks for many mathematical concepts and everyday activities.
