 Today we are going to work on finding the mean also known as the average. The mean, also known as the average, is a central value of a set of numbers. To find the mean, there are two steps. Step one, add up the numbers. Step two, divide by how many numbers you added. Average is commonly used to find average rainfall, average age, or average score on tests. Let's find the mean or average of the numbers 4 and 10. The first step is to add the two numbers. 4 plus 10 equals 14. The next step is to take that number and divide by how many numbers we added. We took our answer, we divided by 2 because there were two numbers. 14 divided by 2 is 7. So 7 is the average of 4 and 14.
