To find the mean average of 20 numbers requires the 20 number to be added together which will take 19 additions and then divide by the number of numbers which will take 1 division

→ 19 additions followed by 1 division, a total of 20 operations are nominally needed to find the mean average of 20 numbers.

To find the average of a given set of numbers, total the numbers and divide that total by the number of members of the set.

The same as you find the average of any other type of number. You add the numbers, then divide the result by the amount of numbers. For example, to find the average of three different numbers, you add them all, then divide the result by 3.

It is the mean average

you add all the numbers then divide it by how many numbers you had

you add all the numbers together then you divide the answer by how many numbers you have..

-- Add the two numbers. -- Divide that total by two.

Add all the numbers together. Then divide by how many numbers there were originally. That is the average.

Add them together and divide them by 2.

Add them together and then divide by 2 :)

The same as you would find the average of other numbers. Add all the numbers together, then divide by the size of the set - by the number that indicates how many numbers you have.

Add them together, divide that total by three

To find the mean, you find the average of the numbers. This means that you just add all of the numbers and then divide that sum by how many numbers are in the list. The sum of all the numbers is 120 which you can then divide by 7 to get 17.143.

Mean is the average. To find the average, add up the group of numbers and divide by how many numbers there were.

Add the numbers together, and then divide by the original amount of numbers in the set.To work out the mean (the average) in maths, you have to add up all of the numbers you are averaging, then divide what you now have by the amount of numbers you started with.

Yes, just add up your numbers and divide that by the number of numbers you have.

add up all the numbers and then divide that number by the number of numbers that you added up.

The Average number is the average of the numbers you're trying to find. To find the average number, you must add up all the numbers first and then divide by the number of numbers. Trust Point Me if this helped, Thanks!
