Chapter 0: Why This Book Is So Cool!
This is where we discover just why the book is so cool, and also why this chapter is numbered '0'.

Chapter 1: Introducing Binary and Hexadecimal

In this chapter we introduce the concepts of the binary and hexadecimal number systems (but in a much more interesting manner than most computer books).

Chapter 2: Computers and Calculators

Here we rampage throughout the insides of a simple computer and calculator, and we also meet our virtual DIY Calculator.

Chapter 3: Subroutines and Other Stuff

In this smorgasbord of a chapter, we first discuss logical, shift, and rotate instructions; and then we plunge headfirst into the stack, subroutines, recursion, and the concept of self-modifying code.

Chapter 4: Integer Arithmetic

This is where we learn the concepts of signed and unsigned binary arithmetic, along with multi-byte data representations. In the labs associated with this chapter we create some integer-based math subroutines for use in Chapter 5.

Chapter 5: Creating an Integer Calculator

This is where things start to get really interesting, because we use the subroutines we developed in Chapter 4 to implement a simple four-function integer calculator.

Chapter 6: More Functions and Experiments

This may be the last chapter, but turn that frown upside down into a smile, because this is where we discover additional projects you can perform (such as floating-point and BCD versions of the calculator), and also how you can compete with other readers to create more and better math routines for your DIY Calculator.

Interactive Laboratories

This is where you will find the interactive laboratories associated with Chapters 2 through 5 (see also a detailed list of these laboratories)

Appendix A: Installing Your DIY Calculator

In this appendix we learn how to install the virtual DIY Calculator presented on the CD-ROM accompanying this book.

Appendix B: Addressing Modes

Here we learn about the various addressing modes supported by the virtual microprocessor powering the DIY Calculator.

Appendix C: Instruction Set Summary

The tables in this appendix are useful for quickly determining which instructions are available with which addressing modes.

Appendix D: Additional Resources

There is a wealth of additional resources for individual readers and educators on the CD-ROM accompanying the book. Also, there are lots of other really interesting books to read. This appendix explains all.
