469 x 999 = 468531



Soln,


Substract 1 from 469 = 469-1= 468


now Substract 468 from 999 following the way : 



  • Hundreds place to Hundreds place : 9 - 4= 5

  • Tens place to Tens place: 9 - 6 = 3

  • Ones place to Ones place : 9 - 8 = 1


Answer is 468531


 


This trick mimics the 9’s complement method used in old subtraction techniques:



  • 9's complement of a digit = 9 - that digit

  • 999 - 468 = (9-4)(9-6)(9-8) = 531


So this works because you're subtracting from 999, not just digit-wise random math.


Final Summary:



  • 999 − 468 = 531 (Valid using normal math or 9’s complement trick)

  • But “468531” is not a mathematical result — it’s just two numbers joined (maybe used in puzzles or codes).
