Watch this video on our YouTube Channel “Mathsbaron” to learn this simple trick.

 

There are 5 symmetrical steps involved over here.

Step 1  -> 9  x  3 = 27 : 7 is kept at the unit’s place and 2 is carried over to the next place value.

Step 2 -> (8 x 3) + (9  x  6) = 24 + 54 =  78 ; 8, the carried over digit 7 is placed to the next place value.

Step 3 -> (7  x 3) + (9  x  6) + ( 9  x  2) =  21 + 18 + 48 = 87 ; 7, the carried over digit 8 is placed below fourth digit.

Step 4 -> (7 x 6) + ( 8 x 2) = 42 + 16 = 58; 8, the carried over digit 5 is placed below fifth digit.
