# What is an Integer in Math?

An integer is a special type of number that we use all the time, even if we don’t realize it. Integers are whole numbers that can be positive, negative, or zero. Think about the numbers you use when you count your toys, the temperature outside, or the number of steps you take. These are all integers!

Types of Integers

1. Positive Integers: These are the numbers you count with, like 1, 2, 3, and so on. They are all greater than zero.
2. Negative Integers: These numbers are less than zero and usually have a minus sign in front of them, like -1, -2, -3, and so on. Imagine you owe someone money; if you owe \$3, you could say you have -3 dollars.
3. Zero: Zero is an integer that is neither positive nor negative. It’s the middle point between positive and negative numbers. For example, if you have zero candies, you have none at all.

Where Do We Use Integers?

Integers are everywhere in our daily lives. Here are a few examples:

• Counting Objects: If you have 5 apples, you’re using a positive integer.
• Temperatures: If the weather report says it’s -10 degrees outside, that’s a negative integer.
• Elevators: When you go to the ground floor, it’s often labeled as zero.

Why Are Integers Important?

Integers help us understand and describe the world around us. They make it easy to count, measure, and compare things. For example, if you score -5 points in a game, you know you need to work harder to get a positive score!
