  ## Calculator math trick with number 12345679
  
  We can use calculators calendars , card packs  for mathematical magics.Today we are working on 12345679 magic with calculator.Its a easy magic and all kids teens and elder people can try .There are few steps to follow.So lets go for that.
  
  Steps are as below
  
  Give a calculator to your friend
  
  Ask him to write 1 to 9 except 8. So it will looks like 12345679 .
  
  Then ask from him to select any one digit from that.
  
  Ask what he has selected
  
  If they choose 7 ,then tell him to multiply the original number 12345679 by 63.
  
  When he multiply the number , answer will shows as 777,777,777
  
  So the magic is that answer is nine digit of selected digit.
  
  What is the trick?
  
  To do the trick you need to multiply the selected number by 9. So in the above example friend said he selected 7. so we multiply the number by 9 in our mind.So the answer is 63. Then we ask to multiply the original number by 63.So we get the answer 777777777.
  
  If your friend chose 9, you’d tell him to multiply by 81 (9 x 9) and they’d get 999999999
  
  Now you know the trick . So lets do the same thing little quicker.

  Example 01:
  
  Ask Some one type 12345679 in calculator
  
  Ask to select any digit.(Suppose he/she selected number 4)
  
  We have to ask multiply the answer by 36 because 4*9 =36
  
  So 12345679 * 36
  
  …………………………………………………………………………………………………………………………………………………………..
  
  Example 02:
  
  Ask Some one type 12345679 in calculator
  
  Ask to select any digit.(Suppose he/she selected number 1)
  
  We have to ask multiply the answer by 9 because 1*9 =9
  
  So 12345679 * 9
