The mean is the average in a set of numbers. To find mean you have to add up all the numbers in a set and then divide what you get by the number of numbers in the set. So this set has 4 numbers thats what you'll divide by. Can you add up the numbers in the set?

anonymous · Answer

so take 6 and divide it by 4

anonymous · Answer

and a negative plus a negative is a negative, i was thinking of a negative times a negative which is a positive, sorry about that

And you know with multiple choice questions in math you can test out each answer to which one is correct. So if you want you could take the numbers in a, b c and d and try multiply them by 4 or adding them 4 times to see if you get 6

anonymous · Answer

and the one that gets you to 6 would be your mean

anonymous · Answer

And thats basically all there is to finding mean. Two steps
1st. ADD together all your numbers in the set
2nd. DIVIDE the answer you get by the # of numbers in the set
