The mean of a number is its arithmetic average.To find the mean of a set of numbers, add up all the numbers, then divide by how many numbers there are.

 Example: What is the mean of 2, 7 and 9? Add the numbers: 2 + 7 + 9 = 18 Divide by how many numbers (i.e. we added 3 numbers): 18 รท 3 = 6 So the mean is 6.
