add them all together and then divide the answer by the number of numbers.
Proper addition will provide you with the sum for your answer. it means that you have to add the numbers ALL TOGETHER. :-)
First you find how many numbers there are, in this case the numbers all together being 8. Then you need to add all of the 8 numbers up and then you get your answer. Example: the numbers are 5,6,10,7,3,1,18,4 .... your answer will be 54 because you add the numbers up and you get your answer. hope this helps!
