1 Set up the long multiplication.
543x36
2 Calculate 3 x 6, which is 18.
Since 18 is two-digit, we carry the first digit 1 to the next column.
3 Calculate 4 x 6, which is 24. Now add the carry digit of 1, which is 25.
Since 25 is two-digit, we carry the first digit 2 to the next column.
4 Calculate 5 x 6, which is 30. Now add the carry digit of 2, which is 32.
Since 32 is two-digit, we carry the first digit 3 to the next column.
5 Bring down the carry digit of 3.
6 Calculate 3 x 3, which is 9.
7 Calculate 4 x 3, which is 12.
Since 12 is two-digit, we carry the first digit 1 to the next column.
8 Calculate 5 x 3, which is 15. Now add the carry digit of 1, which is 16.
Since 16 is two-digit, we carry the first digit 1 to the next column.
9 Bring down the carry digit of 1.
10 Calculate 3258 + 16290, which is 19548
11 Therefore, 543 x 36 = 19548.
The answer is B.19548
