Solution - Long multiplication

Because the tens digit of the multiplicator equals 0, skip to the next digit.

Proceed by multiplying the hundreds digit (1) of the multiplier (100) by each digit of the multiplicand (1,000,000), from right to left.

Because digit (1) is in hundreds place, we shift partial result by 2 place(s) by placing 2 zero(s).

Multiply the hundreds digit (1) of the multiplicator by the number in the ones place value:
1×0=0

Write 0 in the hundreds place.

Multiply the hundreds digit (1) of the multiplicator by the number in the tens place value:
1×0=0

Write 0 in the thousands place.

Multiply the hundreds digit (1) of the multiplicator by the number in the hundreds place value:
1×0=0

Write 0 in the ten thousands place.

Multiply the hundreds digit (1) of the multiplicator by the number in the thousands place value:
1×0=0

Write 0 in the hundred thousands place.

Multiply the hundreds digit (1) of the multiplicator by the number in the ten thousands place value:
1×0=0

Write 0 in the millions place.

Multiply the hundreds digit (1) of the multiplicator by the number in the hundred thousands place value:
1×0=0

Write 0 in the ten millions place.

Multiply the hundreds digit (1) of the multiplicator by the number in the millions place value:
1×1=1

Write 1 in the hundred millions place.

100,000,000 is the first partial product.
