===================== BREAKFAST MATHEMATICS ===================== This is pretty clever how it works out. DON'T CHEAT BY SCROLLING DOWN FIRST It takes less than a minute... Work this out as you read. Be sure you don't read the bottom until you've worked it out! This is not one of those waste of time/joke things, it's fun. 1. First of all, pick the number of times a week that you actually eat breakfast in the morning. (try for more than once but less than 10) 2. Multiply this number by 2 (Just to be bold) 3. Add 5. (for Sunday) 4. Multiply it by 50 - I'll wait while you get the calculator.... 5. If you have already had your birthday this year add 1752....If you haven't, add 1751.... 6. Now subtract the four digit year that you were born. You should have a three digit number. [scroll down for the payoff] - - - - - - - - - - - - - - - - - - - - - - - - - - - The first digit of this was your original number (how many times you eat breakfast each week). The next two numbers are .......... YOUR AGE! (Oh YES, it IS!!!!!) -------------------------------- There are several variations of this formula but I thought it was cool and figured a lot of you are bored just like me. What do you think; neat, waste of time.. what?

Either I am 12 years older than I thought or I am just bad at mental arithmetics ... *looks for calculator* ... ah, the second.

Ahh, the power of algebra. Fortunately for the author of this puzzle, most people don't live to 100 years. It all boils down to this: 100 * {your number} + 2002 (2001 if you haven't had a birthday yet this year) - {your birth year} = magic number = {your number}{your age} No matter what your number, assuming it's greater than one with the exception of zero, it will always be greater than or equal to 100. That leaves 2 digits for your age. But then, if you're 100 or older, it won't quite work, will it?

Simple algebra will reveal that is just simple number manipulation Variables: B = # of times you eat breakfast Y = Year you were born This assumes you birthday already happened this year. B * 2 (or 2B in algebra notation) 2B + 5 50(2B + 5) 100B + 250Simplify 100B + 250 + 1792 100B + 2002Simplify (Hmmm… 2002, significant???? I think so) 100B + 2002 – Y Well, 2002 – Y gives you your age, pretty simple 100B gives you your breakfast number shifted two digits to the left, not exactly rocket science BTW, for those of you over 100, this breaks down

Really, though, it still works if you eat zero breakfasts per week. It just gives you a 3-digit number beginning with zero.

Gabe, You beat me to it! Scott, Neat trick. Reminds me of a similar "mind reading" trick I learned from my father when I was a child. Here is a simplified version, all done by head of course: - take a number (advice: below 10 to make your computations less difficult) - don't tell me, but remember your secret number - multiply by two - add 4 - (a few other operations to make it look more complicated, they influence the end result but are omitted here) - multiply by 4 - now add your secret number again - add 2 - divide by 9 (if that's not possible you made a mistake along the line!) - this time subtract your secret number - multiply by 50 - (more operations to blur what's going on, see above) - OK, I'm going to guess your result now... let's see.. ah! I feel it.. is it 100? The actual operations are changed every time, so it doesn't resemble the same thing over and over again. But it's all mathematics. Cees
