E. Calculator Problems You probably own a calculator and, of course, you are eager to put it to work doing practical math calculations. In this text we include problem sets for calculator users. These problems are taken from real-life situations and, unlike most textbook problems, involve big numbers and lots of calculations. If you think that having an electronic brain-in-a-box means that you do not need to know basic arithmetic, you will be disappointed. The calculator helps you to work faster, but it will not tell you what to do or how to do it. Detailed instructions on using a calculator with whole numbers appears on page 68. Here are a few helpful hints for calculator users: 1. Always estimate your answer before doing a calculation. 2. Check your answer by comparing it with the estimate or by the other methods shown in this text. Be certain that your answer makes sense. 3. If you doubt the calculator (they do break down, you know), put a problem in it whose answer you know, preferably a problem like the one you are solving. Manufacturing The following table lists the number of widget fasteners made by each of the five machines at the Ace Widget Co. during the last ten working days. (a) Complete the table by finding the number of fasteners produced each day. Enter these totals under the column “Daily Totals” on the right. (b) Find the number of fasteners produced by each machine during the ten-day period and enter these totals along the bottom row marked “Machine Totals.” (c) Does the sum of the daily totals equal the sum of the machine totals?
