add all the #s up, then divide by the number of numbers. It's the average. You add all the numbers together and however many numbers there are you divide by that number. For example: 12, 11, 7, and 10 Add them and they equal 40. There are four numbers so you divide 40 by 4 and get 10. That's the mean
There is a formula for adding all the numbers from 1 to n.It is n(n+1) ÷ 2.So the sum of the numbers from 1 to 11 is : 11 x 12 ÷ 2 = 66
