Example
Your numbers are 7, 9, 5, 3, 15, 15. There are 6 numbers all together
To find the mean you need to all all the numbers and divide by how many there.

7 + 9 + 5 + 3 + 15 + 15 = 54

54/6= 9
the mean is when you add all the numbers on the problem together the divide it by how many numbers you have
