What you have to do is you add up all the numbers then you divide by the number of numbers.
ex. Say you have the numbers 45,56,39 and 35 you add them all up 45+56+39+35=175 then you divide 175/4(because there is 4 numbers)=43.75

average
The mean is a set of numbers average. A person can find the mean by adding up all the numbers in the set and then dividing the amount of numbers you added. The median is the exact middle number. Place them in order from least to greatest and see which number is in the middle. The mode occurs most often.
In Math, mean is another way of saying average. If a question asks you to find out the Mean of a set of numbers, it wants you to find the average. To work out the mean (average), you just need to add all the numbers in the setup and then divide by the number in the set. For example, if I had the numbers 3, 5, 6, 2, and 9, I would add them all up and then divide by 5, because there are 5 numbers. So, 3+5+6+10+59=83 83/5=16.6 So the mean, or average of this set of numbers is 16.6.
