Funny Calculator Tricks


Here is a funny calculator tricks to impress and astound your friends and fellows!

  1. Have someone pick a number between 1 and 9.
  1. Now have him use a calculator to first multiply it by 9, and then multiply it by 12,345,679 (notice there is no 8 in that number!).
  1. Have the person show you the result so you can tell him the original number he selected! 
funny-calculator-trickHow? Easy! 

If he selected 5, the final answer is 555,555,555. If he selected 3, the final answer is 333,333,333. 

The Reason:

9 x 12345679 = 111111111.
You multiplied your digit by 111111111.

By the way, that 8-digit number (12,345,679) is easily memorized: only the 8 is missing from the sequence.
