196 Speed Math for Kids
For instance, our methods of division apply to all division problems—
they are not shortcuts applicable to some isolated cases. You can
apply the method of checking answers (casting out nines) to almost
any calculation in arithmetic. It should become an automatic part
of any calculation. We add and subtract just about every day. Th e
methods in this book apply every day. If you are using the methods
every day, how can you forget them?
Th is book doesn’t teach shortcuts—it teaches basic strategies. Practice
the strategies and you will fi nd you are automatically using factors
for simple multiplication and division. You will use the methods for
addition and subtraction. My philosophy has always been, if there is
a simple way to do something, why do it the hard way?
Some of my students have even asked me if using my learning
methods and math methods is really cheating. We have an unfair
advantage over the other kids. Is it ethical? I tell them that the better
students have better methods anyway—that is what makes them
better students. Th ey say, but the other students could do as well as
me if they learned my methods. Sure they could. If you feel strongly
about it, teach the other kids yourself, or lend them your book.
Most of the methods taught are “invisible.” Th at is, the only
diff erence is what goes on inside your head. If someone looked
over your shoulder while you performed a subtraction in class, they
wouldn’t see by watching your work that you are doing anything
diff erent from the rest of the class. Th e same goes for long division,
unless you are using the direct long-division method. So, every
time you perform a calculation you have the choice of using the old
method or the easy method.
You often hear people say they have attended a class or seminar, the
methods were great and easy, but they haven’t used any of it since.
Th ey have wasted their money. Th at is why I tell my students to make
my methods part of their life. You don’t have to perform exercises
every day and practice drills. Th at is a sure way to give up. Just use
