Partial Products Method of Multiplication
In partial products multiplication, each factor is
thought of as a sum of ones, tens, hundreds,
and so on.
For example, in 67 x 53, 67 can be thought of as
60 + 7 and 53 as 50 + 3. Each part
of one factor is then multiplied by each part of the
other factor, and finally, all of the resulting
partial products are added together.
