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.
Step 5 -> ( 7 x 2 ) = 14
vi) Respective digits are added with the carry over digits. So the answer is 207507
