Let your phone number be abcdefg
[ ( 80.(abc) + 1).250 + defg + defg - 250 ] / 2
= 80.250.abc/2 + 250 + defg - 250
= 10000abc + defg
= abc0000 + defg
= abcdefg = your phone number again.
[ ( 80.(abc) + 1).250 + defg + defg - 250 ] / 2
= 80.250.abc/2 + 250 + defg - 250
= 10000abc + defg
= abc0000 + defg
= abcdefg = your phone number again.

LOL, you can make any number of such tricks yourself.














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-if your number is 01-123-4567, the 1st 3 digits are 123)
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
Do you recognize the answer?
