We can make a rectangular array using squares to help us solve this problem. Our multiplication problem is ; therefore, the rectangular array should have  squares across the top row and  squares down the first column. The rectangular array should look like the image below:

We can count the squares to find our answer. The correct answer is is 

In order to solve this problem using multiplication, we must multiply the multiplier by each digit of the multiplicand to get the answer, which is called the product.

For this problem,  is the multiplier and  is the multiplicand. 

First, we multiply  and 

Because the product is greater than , we carry the  and add it to the next product. 

Next, we multiply  and  and then add the  we carried.
