3 digit multiplication

As you already saw 2-digit multiplication, now we see how to slove 3digit ones.

The Rule is    |  X  *  X  |



                                   a  b  c


                               x   d  e  f            
 and answer will be |  X  *  X  |


 same as the 2digit ones.. there must be a minimum of 5 digits in the answer when you multiply two 3-digit numbers.

 coming from right end to left end... (as it is the rule to solve multiplications)
first | denotes               c x f
next X denotes            bf + ec ie., (b x f) + (e x c)
then *  denotes        af + dc + be
next X denotes            ae + bd
 and last | denotes        a x d 



In every digit,, if you have a carry, then u can transfer it to the very next left digit.

and for this 2 digit or 3-digit multiplication, please don't remember  a x f,b x c like that, jut remember the method to solve it.. ie.,  for 2 digit |  X  |
                               and for 3 digit    |  X  *  X  |


here remember..  that star in middle for 3-digit  is like     \|/
                                                                                  .. /|\
