Because the result is greater than 9, carry the 5 to the tens place.

Multiply the ones digit (6) of the multiplicator by the number in the tens place value and add the carried number (5):
6×4+5=29

Write 9 in the tens place.

Because the result is greater than 9, carry the 2 to the hundreds place.

Multiply the ones digit (6) of the multiplicator by the number in the hundreds place value and add the carried number (2):
6×6+2=38

Write 8 in the hundreds place.

Because the result is greater than 9, carry the 3 to the thousands place.

Multiply the ones digit (6) of the multiplicator by the number in the thousands place value and add the carried number (3):
6×3+3=21

Write 1 in the thousands place.

Because the result is greater than 9, carry the 2 to the ten thousands place.
