Unit 3 Lesson 38

What equations would be created from 72 x 43 using the 2 partial products method?

• (70 x 43) + (2 x 43)

• (40 x 72) + (3 x 72)

• (70 x 40) + (2 x 40) + (70 x 3) + (2 x 3)

• 70 x 40 x 2 x 3

What equations would be created from 72 x 43 using the 4 partial products method?

• (70 x 43) + (2 x 43)

• (40 x 72) + (3 x 72)

• (70 x 40) + (2 x 40) + (70 x 3) + (2 x 3)

• 70 x 40 x 2 x 3

Solve: 72 x 43

Answer explanation

Using the 2 partial products method: (70 x 43) + (2 x 43) = 3010 + 86 = 3096

Solve: 35 × 53

Answer explanation

Using the 2 partial products method: (50 x 35) + (3 x 35) = 1750 + 105 = 1855
