Example Question #21 : Whole Numbers

Solve:

Possible Answers:

Correct answer:

Explanation:

In order to solve this problem using multiplication, we must multiply each digit of 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. We start with the multiplier, and multiply the digit in the ones place by each digit of the multiplicand. 

First, we multiply  and 

Then, we multiply  and 

 

Now, we multiply the digit in the tens place of the multiplier by each digit of the multiplicand. In order to do this, we need to start a new line in our math problem and put a  as a place holder in the ones position. 

Next, we multiply  and 

Then, we multiply  and 

Finally, we add the two products together to find our final answer
