Students need the best teacher, so you need examples, because examples are the best
teacher. All the examples in this book are fully worked, and help you do math better.
And this book covers integers, and helps understand what integers are about and how
they mingle with arithmetic operations so that you can not only use integers properly but
can develop your own idea to make use of them, too, solving problems, of course.

It doesn't just cover though, how to do arithmetic with integers, that is, how to do
additions, subtractions, multiplications, and divisions. But it helps also understand the
nature of integers and the nature of arithmetic operations as additions or divisions.
And in particular, it covers the nature and the use of numbers called inverses.
What inverse?

It can be called the negative or the reciprocal depending on the arithmetic operation.
So this book covers those math ideas (concepts), and helps you understand them, and
use them efficiently as well as properly. It can help speed up your calculation, too.
