Your age by chocolate.

[Bloo]

The maths roughly goes:

Step 1: n. Wooo!

Step 2: 2n

Step 3: 2n+5

Step 4: 100n+250

Step 5: 100n+250+1758 (or 1759, but I'll stick with 58 and expand on this bit in a second).

Step 6: 100n+250+1758-Birth... year?

For me thus, I was born in 1990 and haven't had my birthday so would go:

100n+250+1758-1990. If you takeaway the 100n, the numbers on their own work out your age as 1758+250= 2008. While 1759+250=2009. That minus the year in which you were born get your age.

And of course, 100n gives the number, fairly easy.

As you can see, I'm not impressed! And quite bored as I'm willingly doing maths in my spare time.
