Arithmetic 1
Students need the best teacher, so you need examples,
because examples are the best teacher. All the
examples here are fully worked, and help run your math
easier and fast enough.
And this book covers integers, helps understand
what integers are and how they work, and explains
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.
Use integers your way understanding what they are and
how they work.
So it doesn’t just cover 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, along with the
arithmetic. And in particular, it covers the use of
numbers called inverses. What
inverse?
It can be called the negative or the reciprocal
depending on the arithmetic operation.
This book thus, covers the math concept, and helps
understand it, so you get conceptual understanding,
and use it efficiently, as well as properly. It can help
speed up your calculation, too.
You should not just follow steps in the books or
example sets. After your understanding, you should
solve all examples by yourself without looking at the
steps. If only you do it yourself, it’s all yours.
And doing it, put your steps in your writing without
looking at the steps in the solution pages. Also, use a
pen, not a pencil. Making an error, just cross that out
with a single strike only, put the correction next to it,
and move on so that you can check what you have
done. Using erasers, you cannot see what you have
done. We learn a lot from mistakes. And that’s not it.
You can find and get a lot of examples, practice
sets, on this website: www.runmath.com. Thus, you
may want to go to the web page for the book samples
and practice examples, and get them downloaded
and do them all.
You can read or get the book downloaded if click the

it’s much easier
to read.
May your math run very well.
