\nThis 0 acts as a placeholder so that this row is arranged properly. a Question what two numbers multiply to -30 and add to -3.
\nWhen multiplying by larger numbers with two digits or more, use one placeholding zero when multiplying by the tens digit, two placeholding zeros when multiplying the hundreds digit, three zeros when multiplying by the thousands digit, and so forth.
\nNow you multiply 3 4 to get 12, so write down the 2 and carry the 1:
