The mean is the average number.

to find it add all of the number and then divide by how many numbers there are in the calculation.

For example:

10, 3, 4, 5, 23, 21, 12, 9

step 1)

10+3+4+5+23+21+12+9=87

step 2)

I added 8 numbers, therefore to find the average number you have to divide by 8.

85/8 = 10.875

that would be how you find the mean, enjoy averaging
