Which operation would you use to find the average of a set of numbers?

To find the average of a set of numbers, the primary operations involved are addition and division. The process begins by adding together all the numbers in the set. This gives the total sum of the values. Once the total is obtained, it is divided by the quantity of numbers in the set. This final step yields the average.

While addition is integral to calculating the sum, it is not the complete process since the average is defined as the total sum divided by the number of values. Division is the key operation to arrive at the average from the sum. Therefore, identifying addition as the only necessary operation overlooks the importance of dividing by the number of elements. To correctly find the average, one must first perform addition to obtain the sum, followed by using division to get the average.
