The Trachtenberg Speed System Of Basic Mathematics is a guide to performing lightning quick calculations of mind-boggling numbers. Summary Of The Book The Trachtenberg Speed System Of Basic Mathematics is a gateway to making rapid mental arithmetic calculations. The Trachtenberg system is named after Jakow Trachtenberg, the Russian-Jewish engineer who developed this system while he was held in a Nazi concentration camp. Some of these methods, including algorithms for addition, division, and multiplication, have found space in this revolutionary book. The only prerequisite to learning these techniques is an ability to count from 1 to 11. Assuming that the reader is familiar with counting, he or she can easily master the technique and handle large numbers with ease. The system does have some inaccuracies built into it, but it’s found that an accuracy of 99 percent is assured. Many students who had previously failed in lower classes were enrolled in a school that taught the Trachtenberg system as a last resort. After undergoing some training in the system, these students were able to calculate very large numbers with incredible ease. Jakow Trachtenberg believed that each and everyone comes to this world with incredible calculation possibilities. He intended to open this possibility with his system. The Trachtenberg system isn’t tough to learn, not by any stretch of the imagination. It’s simple and immensely effective. That’s because, right from the start, Trachtenberg shared these techniques with children, and especially those children who were doing poorly at school. The Trachtenberg Speed System Of Basic Mathematics contains 8 sections. Through each of these sections, readers will learn such methods as rapid multiplication by the direct method, squares and square roots, and the two-finger method of speed multiplication
