Speed Mathematics Overview

Once you understand the chapters in these tutorials of speed mathematics, you will be able to solve complex mathematical calculations very fast and accurately. You can do these complex mathematical problems mentally.

The principles in these tutorials are taken from various systems like Indian Vedic Mathematics and the German Trachtenberg System.

Vedic Mathematics

Vedic Mathematics is the ancient system of Indian Mathematics. It is originated from "Atharva Vedas", the fourth Veda. This wonderful method is reintroduced to the world by Swami Bharati Krisna Tirtha ji Mahaharaj The book Vedic Mathematics was written by Jagadguru Swami Sri Bharati Krishna Tirthaji Maharaja. He describes Vedic Mathematics as a system of mental calculation.

In Vedic Mathematics, huge problems can be solved very easily and quickly. This is the beauty of it. Vedic Mathematics uses a very simple system. The calculation strategies provided by Vedic mathematics are very powerful and can be applied to various calculation methods in arithmetic and algebra.

The tutorials in this section makes you aware how powerful this system is. Once you learn this system, you can solve big mathematical problems mentally

Trachtenberg System of Mathematics

Jakow Trachtenberg created the Trachtenberg system of mathematics. It is system of quick mental calculation. Researches indicates that the system reduces the time for mathematical operations up to a good extent. Trachtenberg system is not only speedy, but accurate and simple.

Let the total book is 1 part

then, after 1st week remaining part = (1-7/13) = 6/13
after 2nd ----- =(6/13-6/13*5/9)=(6/13-10/39)=8/39

so basically  8/39=96
so 1 = 96*39/8

Let the total number of pages be x

Pages read in first week = 7x/13
remaining pages = x -7x/13 = 6x/13

5/9 of 6x/13 pages were read in second week. ie, 30x/117 pages.
remaining pages = 6x/13 - 30x/117 = 24x/117

24x/117 = 96
x/117 = 4
x = 468

For a square ABCD, angle BAC + angle ACD is equal to
(1)45° (2)60°(3)90° (4)130°

The option is 45 degree. in the square, each angle is 90 degree and required answer for diagonal. so it is 45 degree.

it is 90 degree only. BACis 45 degree and ACD is 45 degree. their sum is 90 degree.

BAC  = 45° and ACD = 45°. So BAC+ACD = 90°

Actually the correct answer is 90 degree. Many people may be getting wrong just because of wrong diagram. correct the diagram and then see the correct answer u would get.

answer should be 180 as every angle of a square is 90 degree
so by adding two angles it should be ( 90+90)=180

AC is a diagonal and hence BAC can't be 90°
