Mastering Numbers is a comprehensive coverage of techniques that enable a person of any age to solve numeracy problems without the use of a calculator. It addresses simplified strategies that enable a person to solve numeracy calculations for all four operations significantly faster than traditional methods. In exploring techniques to solve the single digit multiplication, Mastering Numbers does not rely on a ROTE learning approach but explains the basic patterns that underlie any single digit multiplication. Using the Vedic pattern of multiplication and the system of mental calculation devised by Professor Jakow Trachtenberg, it demonstrates with a step by step process the numerous shortcuts to solve 2 digit by 2 digit multiplications very very quickly. Mastering numbers also explores the 3 digit by 3 digit multiplications that with practice can be solved faster than using a calculator. Dividing any number by 2 digit or 3 digits uses the reverse process of Trachtenberg's multiplication system, where you only divide a number by the first digit of the divisor. Because a book by its very nature is a static learning device, there are both PowerPoints that explain each example in the book and self-correcting worksheets to help master the skills and concepts. These are available by contacting the author at the following website modmaths.com.au Any one (even those who are young at heart) working through the skills of this book, will hopefully become more confident in their approach to Maths. By learning the patterns and techniques, that enable you to solve problems quickly, you may overcome any fear of Maths, enjoy the challenge of solving Maths problems and maybe discover a sense of empowerment that comes with "playing" with numbers.
