Book: The Trachtenberg Speed System Of Basic Mathematics
Can you multiply 5132437201 by 452736502785 in seventy seconds without reaching for your calculator? Well you could if you used the techniques in this revolutionary book, now available in paperback at a time of growing concern about people's numeracy. The system, described as 'the shorthand of mathematics', only requires the ability to count from one to eleven. It is based on a series of simplified 'keys' and is easy to master giving greater speed, ease of handling numbers and increasing accuracy.
must read!!This is one of the best books on basic arithmetic that is constantly being ignored by the educators.
It is far superior to vedic mathematics since it does not require you to keep big numbers in memory during carry over steps in multiplication.
There are very elegant methods for addition (yes, addition!) and also square too and divisions. There are plenty of simple methods of multiplication by single digits (methods you never thought existed) .
The method is truly cool. The logic of how the method is derived is also given in the book at the end. I could do 7 by 7 digit multiplications in less than a minute using this method.
A must read for all indian basic school students. I whole heartedly recommend this book.
