Another word for mean is "Average"

Let's think of a question where you can intuitively answer this question.

Let's say 5 kids together ate 20 pieces of candy. The first kid ate 2, the second 3, the third 4, the fourth 5, and the fifth 6. On average, how many pieces of candy did each kid eat? The answer immediately leaps to our mind: 4! which is simply "total number of candy eaten divided by the number of kids".

Therefore, mean of some numbers = average of some numbers = total / (# of numbers).

E.g. mean of 2, 3, 4, 5, 6 is (2 + 3 + 4 + 5 + 6)/5 = 4.

If you are given a set of numbers, count how many you are given. Add all the numbers up. Then divide the total by the count.

The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are.
