This book teaches elementary mathematics that will be needed in basic computer programming. Chapter 1 begins with the division algorithm and how to put numbers into different bases. It proceeds to elementary modular arithmetic.

Chapter 2 applies the modular arithmetic developed in the first chapter to issues associated with the development of a calendar system for computer programming.

Chapter 3 introduces sets, logic, functions, and true tables.

In Chapter 4, we introduce logic gates and develop the adder all the way down to the transistor level.

The fifth and final chapter includes various topics that arise naturally from what was covered earlier: shifts, multiplication, and subtraction.

The book is written for the intelligent learner whose interest is in computer programming rather than mathematics itself.
