#### Answer

It is a highly inefficient algorithm because of the number of steps required to find the answer. For example, to add (234 + 567), we will have to repeat the addition of the value 234 to a running sum 567 separate times. When we do multiplication the “traditional” way that we learned in grade school, we have to carry out far fewer operations. (We will learn much more about how to evaluate the efficiency of algorithms in Chapter 3.)
