Is there more than just the operation of addition in arithmetic? Can you subtract any number from another without borrowing? Can you multiply without carrying? Why, when doing a division problem, do you multiply, subtract, etc.? Is there a real mathematical basis behind the Order of Operations? Why does 'invert and multiply' work when dividing fractions?

Is there more than just the operation of addition in arithmetic? Can you subtract any number from another without borrowing? Can you multiply without carrying? Why, when doing a division problem, do you multiply, subtract, etc.? Is there a real mathematical basis behind the Order of Operations? Why does 'invert and multiply' work when dividing fractions? What are common denominators? Why do you not need common denominators to multiply fractions? If you are unsure about any of the answers to the above questions then you should read this book. It is sure to take some of the 'mystery' out of arithmetic as well as adding to your understanding. Mathematics teachers: You can bring a fresh approach to teaching arithmetic, and hopefully a better understanding for your students. Parents: No more do you have to say 'I don't understand the new math.' This is the old math from a new perspective. Anybody else: This is a 'fun' book to read, especially for a math book. It will not be long before you are seeing the Hermit move in and out of his cave, scratching his head, and trying to explain some mathematical property.
