Publisher’s
write-up:
‘”I
don’t like math!” “When will I ever use this?” “What’s the point?” If you’ve
ever thought any of the above, discover the game of 9 = 0! This is where the
FUN begins! You’ll find by using the right systems, you’ll be able to simplify
large numbers, and make them melt like margarine on a hot skillet! You’ll be
introduced to a shorter method of solving division problems. You’ll also
discover how varied and colourful math history is, and be introduced to the
curious world of “amicable numbers”. Along with these fun new tools in your
“pocket”, you’ll also be introduced to the mind-set of innovators who have
accomplished feats beyond what everyone else thought they were capable of doing.
Step inside this new world of math, and you will Fear No Numbers!’
This is a book dealing with certain
arithmetic techniques written by Jose Paul Moretto; who happens to have a very
interesting profile, having served in the French Air Force, then going on to
work in the R&D of Citroen and eventually, started teaching mathematics in
United States.
This book deals with two concepts, the Proof by Nine and the MaXima; techniques he has devised to
obtain solutions for multiplication and division problems. These techniques are
meant for verifying the solution obtained by multiplication or division and
ensuring that they have been computed correctly. Along with that, the author
has also provided with various anecdotes and also has quoted a lot of people to
help dispel people’s fear of mathematics.
The solutions offered by him were quite
simple and very easy to understand and also, quick to execute, when you are to
verify the result of your computation in an examination. Additionally, I liked
it as to how the author gave an elaborate write-up about how to compute each of
his solutions and also provided a simpler method to solve division problems
which could be useful for children undergoing primary education.
The author promised that by the end of this
book, we would not fear numbers and thus, the title of the book does make you
develop very high expectations but ultimately, what he has offered as solutions
are merely methods to verify the computations which you still do out of fear.
Moreover, these solutions seem simple to me as a 23 year old today, but I am
unsure as to how a 10 year old would react to learning something beyond what is required and thus, might
probably appeal only to maths enthusiasts. Moreover, I had no idea why he had
to introduce the concept of amicable pairs considering he was not even dealing
with the topic and did not use that anecdote anywhere else in the book.
I would conclude by saying that the
techniques that he seems to offer are effective, and I might have probably had
a more accurate way of checking my answers back in school and I believe that
this is an ideal book to be read by children between the age 8 – 12. I would
award the book a rating of six on ten.
Rating
– 6/10
Have
a nice day,
