Solution - Long multiplication

Start by multiplying the ones digit (5) of the multiplier 675 by each digit of the multiplicand 20,000, from right to left.

Multiply the ones digit (5) of the multiplicator by the number in the ones place value:
5×0=0

Write 0 in the ones place.

Multiply the ones digit (5) of the multiplicator by the number in the tens place value:
5×0=0

Write 0 in the tens place.

Multiply the ones digit (5) of the multiplicator by the number in the hundreds place value:
5×0=0

Write 0 in the hundreds place.

Multiply the ones digit (5) of the multiplicator by the number in the thousands place value:
5×0=0

Write 0 in the thousands place.

Multiply the ones digit (5) of the multiplicator by the number in the ten thousands place value:
5×2=10

Write 0 in the ten thousands place.

Because the result is greater than 9, carry the 1 to the hundred thousands place.

100,000 is the first partial product.

Proceed by multiplying the tens digit (7) of the multiplier (675) by each digit of the multiplicand (20,000), from right to left.

Because digit (7) is in tens place, we shift partial result by 1 place(s) by placing 1 zero(s).

Multiply the tens digit (7) of the multiplicator by the number in the ones place value:
7×0=0

Write 0 in the tens place.

Multiply the tens digit (7) of the multiplicator by the number in the tens place value:
7×0=0

Write 0 in the hundreds place.

Multiply the tens digit (7) of the multiplicator by the number in the hundreds place value:
7×0=0

Write 0 in the thousands place.

Multiply the tens digit (7) of the multiplicator by the number in the thousands place value:
7×0=0

Write 0 in the ten thousands place.

Multiply the tens digit (7) of the multiplicator by the number in the ten thousands place value:
7×2=14

Write 4 in the hundred thousands place.

Because the result is greater than 9, carry the 1 to the millions place.

1,400,000 is the second partial product.

Proceed by multiplying the hundreds digit (6) of the multiplier (675) by each digit of the multiplicand (20,000), from right to left.

Because digit (6) is in hundreds place, we shift partial result by 2 place(s) by placing 2 zero(s).

Multiply the hundreds digit (6) of the multiplicator by the number in the ones place value:
6×0=0

Write 0 in the hundreds place.

Multiply the hundreds digit (6) of the multiplicator by the number in the tens place value:
6×0=0

Write 0 in the thousands place.

Multiply the hundreds digit (6) of the multiplicator by the number in the hundreds place value:
6×0=0

Write 0 in the ten thousands place.

Multiply the hundreds digit (6) of the multiplicator by the number in the thousands place value:
6×0=0

Write 0 in the hundred thousands place.

Multiply the hundreds digit (6) of the multiplicator by the number in the ten thousands place value:
6×2=12

Write 2 in the millions place.

Because the result is greater than 9, carry the 1 to the ten millions place.

12,000,000 is the third partial product.

100000+1400000+12000000=13500000 long addition steps can be seen here

The solution is: 13,500,000
