next, the hundreds-column. find the product of the hundreds-multiplier and the multiplicand and write it down in a row—call it the "hundreds-row"—under the tens-row, but shifted one more column to the left. that is, the ones-digit of the hundreds-row will be in the hundreds-column; the tens-digit of the hundreds-row will be in the thousands-column; the hundreds-digit of the hundreds-row will be in the ten-thousands-column. if the hundreds-row has four digits, then the first digit will be the beginning of the hundred-thousands-column.
