Example:
Example: Suppose you want to divide the total annual production for one of your
firm’s products (429,000) by the number of retail outlets (987) in order to
calculate the average number distributed by each outlet. Unfortunately, you
mistakenly key in the number of outlets as 9987 rather than as 987. It’s easy to
correct:

About 43 products per outlet — but
that seems too low!
