A Mathematical  Illusion

  • Choose a number from 1-9
  • Subtract 5 ( its OK if this is now a negative number, just pretend it isn't ! )
  • Multiply by 3
  • Multiply by the same number
  • Add the digits as a new sum until you get only one digit ( i.e. 36 is 3+6 =9 )
  • If the number is less than 5, add 5. Otherwise subtract 4.
  • Multiply by 2
  • Subtract 6
  • Coincide the digit to a letter in the alphabet 1=A, 2=B, 3=C, etc...
  • Choose a country that begins with that letter
  • Take the second letter in the country name then choose an animal that begins with that letter
  • Think of the basic color of that animal.
