Here is a cool math trick about your phone number:
1. Grab a calculator. (you won't be able to do this one in your head) 2. Key in the first three digits of your phone number (NOT the area code) 3. Multiply by 80 4. Add 1 5. Multiply by 250 6. Add the last 4 digits of your phone number 7. Add the last 4 digits of your phone number again. 8. Subtract 250 9. Divide number by 2
What number did you get?

1. Gotta have something to do with adding that 1 |

Too bad I didn't take a number theory class...
I get my phone numbers both times I tried it.

you can leave out the 1 and the subtracting 250 and it should still work. Tricks like these boil down to "multiply by 2, ok now divide by 2. Look! you get the same number!"

4. If you break down the formula |

Edited on Tue Mar-09-04 03:16 PM by TlalocW
It comes down to 10,000 X + Y where X is the first 3 digits of your phone number, and Y is the last four digits. Multiplying say, 555 by 10,000 gives you 5,550,000. Adding the last four digits - say 1212 then gives you 5,551,212, which is your phone number.
The formula (after you go through all of the instructions) is:
{250(80(X) + 1) + 2Y - 250}/2 -> {20,000X + 250 + 2Y - 250}/2 -> {20,000X + 2Y}/2 -> 10,000X + Y

1. Grab a calculator. (you won't be able to do this one in your head)
OK
2. Key in the first three digits of your phone number (NOT the area code)
x
3. Multiply by 80
80x
4. Add 1
80x + 1
5. Multiply by 250
250(80x + 1) = 20000x + 250
6. Add the last 4 digits of your phone number
20000x + 250 + y
7. Add the last 4 digits of your phone number again.
20000x + 250 + 2y
8. Subtract 250
20000x + 2y
9. Divide number by 2
10000x + y
x is a 3-digit number, so 10000x has the form XXX0000. y is a 4-digit number, so adding it to XXX0000 gives XXXYYYY, which is your phone number.

11. Here try this one ... |
|
Take your favorite Number Add 1 Subtract 1 The resulting number should be your favorite number. Amazing isn't it.
If you can come up with one of these that does not include entering all of the information that it claims to provide ... then I'll be impressed.
Cheers Drifter
