This is cool!
YOUR AGE BY DINER & RESTAURANT MATH
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 things, it's fun.
1. First of all, pick the number of times a week that you would like to
go out to eat. (more than once but less than 10)
2. Multiply this number by 2 (just to be bold)
3. Add 5
4. Multiply it by 50
5. If you have already had your birthday this year add 1758...
If you haven't, add 1757.
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 go out to restaurants in a week.)
The next two numbers are
YOUR AGE ! ------ (Oh YES, it is!)
THIS IS THE ONLY YEAR (2008) IT WILL EVER WORK

Hello jess368,
It was interesting!:-)
It is actually based on simple mathematical modeling. You can make your own model by knowing how to play with the numbers. Let me try one!:-)
I think if you replace first multiplier from 2 to 10, and second from 50 to 10 and then add 1957 or 1958 (depending on whether your birthday has passed this year or not, just like your model), you will get a number which has same meaning as you described. That is, the first number would be number of times one goes to restaurant and later two numbers, the age!:-) I can try other combinations too!

This is a pretty fun test! Granted my math skills aren't that great so I used a calculator ;-)
Commenting that this is the only year it will work is wrong though cuz I've done this before haha. I'm not sure how though :)

Sorry to chime in here, CherBear04, but the poster is right that this exact formula will only work for this year. For next year, to get your age right, you will at least have to add '1' more in step 5 i.e. you will have to use 1758 instead of 1757, and 1759 instead of 1758! you can verify it by doing calculations for next year!:-)

This isn't the only year it will work. I did it last year too. I don't know why people say it will only work in a certain year.
It does work though. There are certain numbers which, when used for any equation, will come up with the same answer (or at least the same basic formula) and I think that's how it works.

Oh I see, well it will still be the same formula though. Just with one or two digits changed to suit the year so in a way it will always work and in a way it won't because it will need to change.
