# verrrry interesting ....

Work it out as you read.

Be sure you don't read to the bottom until you've worked it out.

1. First of all, pick the number of times a week that you would like to ski. (Try for more than once but less than 10)

2. Multiply this number by 2

4. Multiply it by 50. ( We'll wait while all non-CPA's get their calculator out.)

6. Now subtract the four digit year that you were born. You should have a three digit number.

The first digit of this was your original number: (i:e, how many times you want to ski each week)

The next two numbers are...........YOUR AGE!

(Oh yes, it is!)

THIS IS THE ONLY YEAR IN OUR LIFETIME THAT THIS WILL EVER WORK, SO SPREAD IT AROUND WHILE IT LASTS.
wow, it really works
Nooooooo! How'd that work?! It works!
Wait a minute, wait a minute, how on earth did you do that????????
ahhh... a mathemagician.
Numerical party tricks like this are always great fun, but are always constructed in more or less the same way. So, in keeping with my role as a semi-official Epic weenie, in case someone has never seen how these tricks really work and is curious, here's the inside scoop.

Let:

SDPW = number of ski days per week (1-9) you selected

BY = birth year (eg, 1960)

AGE = (2002 - BY) if you had your birthday yet this year (Case A)
= (2001 - BY) if you have NOT had your birthday yet this yr (Case B)

He then has us calculate a "MagicNumber" using one of 2 procedures:

Case A:

MagicNumber = (SDPW*2 + 5) * 50 + 1752 - BY
= 100*SDPW + (2002 - BY)

But, from above we see that (2002 - BY) = AGE in case A, therefore:

MagicNumber = 100*SDPW + AGE

In Case B, the formula is slightly different:

MagicNumber = (SDPW*2 + 5) * 50 + 1751 - BY
= 100*SDPW + (2001 - BY)

But, from above we see that (2001 - BY) = AGE in case B, therefore, once again:

MagicNumber = 100*SDPW + AGE

So, the first digit (ie, the hundreds place) of the "magic number" will always be exactly equal to number of ski days per week, while the next two digits (the tens and units places) will always contain your age. QED.

Now, will someone please tell me how many more days do I have to twiddle my thumbs like this waiting for the first snow to get here?
