Annual Arithmetic

1: Choose any positive integer
2: Triple it.
3: Multiply the result by three (yes, again).
4: If the number contains more than one digit, add them all up.
5: If the result of step 4 results in a number with more than one digit, repeat step 4.
6: Add ten.
7: Store your current result in memory (MM).
8: Decrease the number by one.
9: Subtract the result from 100.
10: Store the new result in memory (NN).
11: Concatenate the two numbers in memory - MMNN.
12: Subtract MMNN from the current year, 2010.

The end result is my new age! :-)
