Let's say you're working with the numbers 2, 3, and 4. Add them up: 2 + 3 + 4 = 9. In this case, you're working with 3 numbers. Now take the sum of the numbers, 9, and divide it by the amount of numbers, 3. 9/3 = 3. The mean, or the average of all the numbers in the set, is 3. Remember that you won't always get a nice even number for your answer.
