354 Presents - Doing the Maths!

Now look here, KP

I wish you wouldn\'t send me the same 

354 presents each year

If I\'ve got my calculations right

 

I mean the 12 Days of Christmas

That\'s Day 1 - A partridge in a pear tree (Total so far: 1 present)

Day 2 - Two turtle doves AND a partridge... (2 presents on Day 2. Total so far: 1+2 = 3 presents)

On Day 3 add the totals for each day so far: 1+2 = 3

Day 3 - and so on (3 presents on Day 3. Total so far: 1+2+3 = 6 presents)

On Day 3 add the totals for each day so far: 1+3+6 = 10

And so on up to Day 12

See the video

Save me writing out each day\'s presents!

 

When you get to day 12 you should be adding

1+3+6+........up to Day 12\'s total

It should give you a grand total of 354, I think

 

I wouldn\'t mind if they were different gifts each years

But I got about 5,483 partridges

12,846 swans a-swimming

15,637 geese a-laying

And thousands of other things now

All in the song!
