How do you calculate the number of gifts received in the twelve days of Christmas?

Answer 1

The quickest way is to take the number of gifts multiplied by how many days they were given. The partridge was one gift, given 12 times. The turtle doves were 2 gifts, given 11 times and so on. The math looks like this:

1 X 12 = 12

2 X 11 = 22

3 X 10 = 30

4 X 9 = 36

5 X 8 = 40

6 X 7 = 42

7 X 6 = 42

8 X 5 = 40

9 X 4 = 36

10 X 3 = 30

11 X 2 = 22

12 X 1 = 12
