Multiplication Using Partial-Products By M. Thornton
23 x 46 = 2 3 x 4 6 20 x 40 800 20 x 6 120 3 x 40 120 3 x 6 18 1,058
Now you try! • 13 x 28 = First, multiply 10 x 20= 200 Then, multiply 10 x 8 = 80 Next, multiply 3 x 20 = 60 Finally, multiply 3 x 8 = 24 Add the products to get 364!
32 x 54 First, multiply 30 x 50= 1500 Then, multiply 30 x 4 = 120 Next, multiply 2 x 50 = 100 Finally, multiply 2 x 4 = 8 Add the products to get 1,728!
