I'm a little angry yes angry writing this because I feel for the people out there that struggle with math you never stop to think there is another way. This book convinced me that math can be enjoyable if you give yourself time to practice the different techniques within this book.
I never heard of complement addition or subtraction before and when I finally understood it I urge any parent, teacher, or anyone still foggy on the fundamentals of math to pick this book up.
But I was very disappointed. In today's world I use a calculator for the important stuff. I don't want a book of calculation "tricks" but neither do I have any interest in dealing with pencil and paper or playing with my fingers. Not bad. There are elements to committing speed math to memory.
It has these. I am in whole hearted agreement with the reviews already listed on this marvelous little book and the suggestions made about its usage and potential impact; just thought I would add my own personal experience.
I am an undergraduate Maths major who managed to slip through elementary, middle, high-school, and even some of college without ever learning my times tables or memorizing the first 25 or so possible additions and subtractions like most American school children.
I spent years thinking that I was terrible at Math and hated it in high school; partly from frustration with constant arithmetic errors supposedly the easiest field in Mathematics and partly, like most others, from just awfully lacking curriculum and uninspired teachers.
Some time ago I stumbled upon this little volume in a used bookstore and I never looked back. Developing a comprehensive and unified method of arithmetic based upon the modern Japanese Soroban techniques, Stoddard does us all a huge favor and makes arithmetic something quick, easy, and satisfyingly, consistently, accurate.
With wit and clarity he lays forth streamlined methods of Addition, Subtraction, Multiplication, Division, Results verification; and shows one how to combine his methods with the best of the standard short-cuts factoring, aliquots, etc A thorough working of this book will leave anyone who grew up under the standard American methods of arithmetic with feelings of anger and frustration at all the wasted hours of figuring, all jumbled with feelings of clarity and elation in their new found powers.
You will literally not need a calculator ever again for any basic operational calculation; more difficult extended calculations will be able to be figured and checked for accuracy!!
We certainly need, right now, starting today, yesterday even, to immediately begin introducing these methods in our elementary and middle schools, and to make them standard throughout high school, college, and our culture in general.
Every one should have the pleasure of knowing how easy it actually is to deal with numbers. Want to make others believe you are a genius? Need to make a good impression during a job interview that likes to throw mental math problems to test an applicant's intelligence? If so, this book is an excellent foundation to mastery of mental arithmetic. I've been "ok" with arithmetic since childhood, and certainly no math prodigy by any stretch of the imagination.
Some of the things I discovered on my own are elaborated on and synthesized here in this book. Skill with numbers, for the most part, is acquired, not something you are "born with.
Sadly, the vast majority of the population is discouraged from higher mathematics because of poor teaching methods during the critical childhood period.
Engineers love showing off what they can do after attending a class. The methods are more than techniques for fast calculation. They develop strategies for general problem solving.
Speed Mathematics -Quick Metal Maths tricks (Ebook PDF)
If you don't know , or haven't been taught how to solve a problem, you will work out your own method. Many students have already learnt these methods and developed reputations for being mathematical prodigies. Here is a short excerpt from some of my material on Easy Mathematics where I illustrate how an easy method can improve your ability. What would you think if I told you that you could master your tables up to the ten times table in less than 15 minutes?
And your tables up to the twenty times table in less than half an hour? You can, using the methods we explain in this chapter. We only assume you know the two times table reasonably well, and that you can add and subtract simple numbers. Let's go straight to the method. Here is how you multiply numbers up to ten times ten.
Elementary Algebra Textbook Solutions Manual
We'll take 7 X 8 as an example. Now go to the first number to be multiplied, 7. How many more do you need to make 10? Write 3 in the circle below the 7. Now go to the eight. What do we write in the circle below the eight?
How many more to make 10? The answer is two. Write 2 in the circle below the eight.

Your work should look like this. We now take away diagonally.
Take either one of the circled numbers 3 or 2 away from the number, not directly above, but diagonally above, or crossways. In other words, you either take 3 from 8 or 2 from 7.
Either way, the answer is the same, 5. This is the first digit of your answer.
You only take away one time, so choose the subtraction you find easier. Now you multiply the numbers in the circles. This is the last digit of your answer. The answer is This is how the completed sum looks. Let's try another, 8 times 9. How many more to make ten? The answer is 2 and 1. We write 2 and 1 in the circles below the numbers.
What do we do now? We take away diagonally.It sounds interesting. Learn more about site Giveaway.
If you are a seller for this product, would you like to suggest updates through seller support? Well, you will be able to do them after finishing this book.
The full answer is 9, I never heard of complement addition or subtraction before and when I finally understood it It is an unfair rule, but it is a rule just the same.
