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.

Option (c) 90
The diagonals bisect the angles making 45 each and the sum is 90

For square ABCD,  angle BAC = angle ACD = 45°
angle BAC + angle ACD = 45° + 45° = 90°

My 3- digit number has a 4 in the hundreds place. it has a greater digit in the tens place than in the ones place. The sum of the digits is 6. what is my number?

let the 3 digit number be 4xy

4 + x + y = 6
or x+y=2

So there are 3 possibilities - (x,y) can be (2,0) or (1,1) or (0,2)

But, it is given that x > y
so (x, y) can be only (2,0)

Number is 420

x+y cannot be 2.cause it has been mentioned that the sum of these 2 numbers is 6 n not 2. so,4+x+y=10. i hope im right.

Anan, Jay is right. sum of the digits is 6. Therefore 4+x+y is 6.

You have taken x+y as 6, missed the digit 4

u can solve in 3 sec......

it should be relevant to 100(.. like 101,105,107,98,96,94.....and so on,any value near to 100)
125=100+25(now add cross values)

115+25=125+15=140(both side sum is equal)
115    +15
125    +25
140 keep 2 zeros along with 140 bcz its 100 place digits,so
