Amazing Pre-shool Maths Formula

Feeling dull on the black and white accounting system, worsen by Monday blue effects and a hazy morning? Try this funny maths...reproduce any given 7-digits code (e.g. last seven digits of a cellphone number, ICQ number, etc), after applying that number with a series of simple pre-school calculations:

  1. Enter first 3 digits of the 7-digit code to your normal calculator.
  2. Multiply the number by 80
  3. Add 1 to the previous result
  4. Multiply the result from previous step by 250
  5. Plus the result with the last 4 digits of the number
  6. Plus last 4 digits of number once again to the previous step result
  7. Minus it with 250
  8. Divide it by 2
  9. Bingo! That is the original 7-digits code.
