Integers include positive whole numbers, negative whole numbers, and zero.
The "set of all integers" is often shown like this:
Integers = {… -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, …}The dots at each end of the set mean that you can keep counting in either direction. The set can also be shown as a number line:
The arrows on each end of the number line mean that you can keep counting in either direction.
Adding and Subtracting IntegersLooking at a number line can help you when you need to add or subtract integers.
Whether you are adding or subtracting two integers, start by using the number line to find the first number. Put your finger on it. Let's say the first number is 3.
- Then, if you are adding a positive number,move your finger to the right as many places as the value of that number. For example, if you are adding 4, move your finger 4 places to the right. 3 + 4 = 7
- If you are adding a negative number, move your finger to the left as many places as the value of that number. For example, if you are adding -4, move your finger 4 places to the left. 3 + -4 = -1
- If you are subtracting a positive number, move your finger to the left as many places as the value of that number. For example, if you are subtracting 4, move your finger 4 places to the left. 3 - 4 = -1
- If you are subtracting a negative number, move your finger to the right as many places as the value of that number. For example, if you are subtracting -4, move your finger 4 places to the right. 3 - -4 = 7
Here are two rules to remember:
- Adding a negative number is just like subtracting a positive number. 3 + -4 = 3 - 4
- Subtracting a negative number is just like adding a positive number. The two negatives cancel out each other. 3 + 4 = 3 - -4

Which of the following sets of numbers contains ONLY integers?
You did not provide any choices to choose from, but you can tell this way. Integers include whole numbers (which are the counting numbers and zero) and their negatives. So -5, 0, 1, 5023, -5435345435, are all integers. No fractions or decimals are included in the set of integers.
