Practice Test 3

Compute $47 \times 32$ using the standard algorithm. In the ones-place step, you multiply $47 \times 2$. In the tens-place step, you multiply $47 \times 30$. Which statement about combining partial products is correct (and uses place value correctly)?

An area model for $34 \times 26$ is split into $(30 + 4)$ and $(20 + 6)$. The partial products should be $30\times20$, $30\times6$, $4\times20$, and $4\times6$. Which value is the correct total product (showing the partial products are combined correctly)?
