1. Let's start by understanding what an average is. The average (or mean) of a set of numbers is found by adding all the numbers together and then dividing by how many numbers there are. 2. For example, if you have the numbers 2, 4, and 6, you add them: $2 + 4 + 6 = 12$. 3. Then, since there are 3 numbers, you divide the total by 3: $\frac{12}{3} = 4$. 4. So, the average of 2, 4, and 6 is 4. 5. This method works for any set of numbers: add them all up, then divide by how many numbers you have. 6. Remember, the average gives you a number that represents the middle or typical value of the group.
