Dear Amy: What is a perfect number? — Jasmin, Cavite City, Philippines

Dear Jasmin: A perfect number is a whole number and an integer greater than zero that has a special property. When you add up all the factors less than the number, it should equal that number. For example, 6 is a perfect number. Its factors, 1, 2 and 3, add up to 6. There aren't very many known perfect numbers. So far, only 47 have been found.
