You add the scores together and then divide by the number of scores.
So if you rolled a dice and your scores were,
3, 5, 2, and 6
You would add these together, getting 16, and then you would divide this by 4 (because you have 4 scores) and so your mean would be 4 (16/4=4)
sum of scores / number of scores = mean.
Hope this helps.
