The average (arithmetic mean) is the sum of the values divided by the number of values.
Example : 5, 9, 10
Their sum is 5+9+10 = 24 and there are 3 numbers

The average of a set of numbers is defined as the sum of those numbers divided by the number of numbers. If the average is given, multiply that by number of items in the set including the missing number. Subtract the sum of given numbers from this quotient and the missing number is revealed.
average
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.
the mean or average of the set
Well, isn't that a happy little question! To calculate numbers in a math data set, you can start by finding the mean, which is the average of all the numbers. Then, you can find the median, which is the middle number when the data set is ordered from smallest to largest. And finally, you can find the mode, which is the number that appears most frequently in the data set. Just remember, there are many ways to appreciate the beauty of numbers!
