About the homework problems 1/14
Session Links
  • Some problems require thought
    • Some are similar to — but go beyond — what we show you in demonstrations and in these notes
    • This is meant to prepare you for what you will encounter at work
  • Many problems are “word problems”
    • You’ll have to read and understand what they tell you and what they ask for
    • You’ll have to convert that understanding into spreadsheets
  • You might feel that the wording of some problems is ambiguous
    • This too is meant to prepare you for what you’ll encounter at work
    • Resolving the meaning is part of what we’re trying to teach
  • If you’re unsure of what is wanted:
    • Consult your teammates
    • Send mail to the course discussion list
    • In some cases, it’s possible that we might not provide a resolution that you find satisfactory in advance of the due date

Some students feel that homework problems should be directly parallel to what we discuss in demonstrations and in these notes. We disagree, because exact parallelism isn’t available in the real world.

When you try to apply in the real world what we’ll be showing you, the real world will make no such commitment to you. You need to practice what we show you, that much is true. But you also need to practice applying what we show you to situations that aren’t quite the same as what we presented. Only when you can do that will you have learned anything useful, that will distinguish you as an employee and professional of outstanding capability. Some of the homework we assign is intended to “stretch” you in this way.

A similar situation exists in the area of ambiguity. Some of the word problems we assign can be interpreted in different ways. In the real world, ambiguity abounds. Our homework is intended to give you practice in determining the most probable interpretation.

Even with all of that, you still have an advantage over the real world in this course. That advantage derives from the knowledge that the critical steps needed for each homework assignment are in some way related to the topics of that assignment. In the real world, you’ll find no such guidance.

Deciding What to Read

The first homework assignment has a fair amount of reading attached to it. Some students feel that the best approach is to read it all, and then try to do the homework. For most of us, such an approach doesn’t work very well.

Before you begin the course, read the general material, such as “Getting Started,” “Software You Need for This Course,” and “How to Work.”

Later, as you begin the homework, let the homework drive your reading choices. For instance, the first homework assignment does require that you master certain techniques. Read “Names” and “The Ripple Principle.” Then, if something confuses you, read up on it: examples are “The Basics of Recalculation” and “References.” Learning something when you need it, and only when you need it, is usually the best way to go.

Avoid Redundant Parentheses

Parentheses sometimes make a real difference. For instance A1*B1+2 is very different from A1*(B1+2). But A1*(B1*2) is exactly the same as A1*B1*2. When the parentheses don’t make any difference in the value of the result, it’s not usually a good idea to include them. They tend to make the formulas harder to read, and there’s always the chance that you’ll put them in the wrong place. More
