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