Division by Nikhilam, 18 mathematics tricks and fun  In the current system, We need to use trial digits when dividing with big divisors.in the vedic system We can  add or subtract for division which makes it easy. Here there are 4 methods of which argumental division  I am omitting since it is good for algebraical divisions  and not for arithmetical computations. (1)Nikhilam method used for big numbers,  (2)paravartya method for smaller digits.Best of all  these and (3)quick one is Straight Division. Nikhilam Sutra is used as said earlier when divisor is  with bigger digits like 6,7,8,90.we should find the complement of this and divide.  Here we have 3 examples. First 2 are two digit  numbers to be divided by 9.The third one is three digit dividend. In all these divisor is 9.The complement  of 9 is 1. We will write this as 9/1, as shown.Now We should count the digits in the divisor and that much  digits we should count...

Riddles, The 17th Lesson of Mathematics Tricks and Fun Hello friends,This is the 17th lesson of mathematics  tricks and fun tutorial . I am Dr Prema B Sejekan.  Today we shall have a quiz test from the portions we  have studied till now. All these days we have studied various methods for multiplication from Vedic mathematics .This helps us to quickly answer in  seconds multiplication with big numbers. Now let us  start the quiz. Can you answer these three questions ? What is the square of 999999 and 666666 and 333333.    You can do the calculation all three in 30 seconds. back ground music will play during waiting period. Answer is Sequence off five 9s, 8sequence of five 0s  and 1  Second question sequence of five 4s , 3 and sequence  of five 5s and 6 Third question. Sequence of five 1s , 0 and sequence of five 8s, and 9. Isn't it interesting.we have used here the special code  one more one less..y...

Tesla code Tesla-Code,16th-Lesson-ofMathematics-Tricks andFun When we hear Tesla we remember first Tesla cars and Elon Musk the Business Magnate . Today we are going to study the tesla code 369 . Hello friends ,welcome to the 16th class of mathematics Tricks and fun.I am Dr Prema B Sejekan. Nikolas Tesla strongly believed “Knowledge of the The Magnificence of the digits 369 holds the Key to the understanding of the Universe”. Now who is Nicolas Tesla?  Nicolas Tesla was born in 1856 and expired in 1943 . A Serbian American by birth, he was a great inventor engineer , who had a lot of patents to his credit. He patented rotating magnetic field used in alternating current. Tesla and George Westinghouse created the Hydroelectric power plant at Niagara falls .Tesla coil used in wireless and radio technology is another important invention. In fact Nicholas Tesla in his childhood used to passionately dream of harnessing electricity from Niagra Falls and he co...

 Maths Tricks and Fun 15-digital-sum Hello friends today we will study how multiplication becomes easy by the use of digital sum .What is  digital sum? It is the sum of the digits of a number  . Here its use in multiplication of big same digit  numbers ,their squaring and cubing are discussed.  Here use of digital sum in squaring of 4digit number  is shown the digit is 4 ie (4444) are to be squared..so  first we multiply the two outer fours 4×4 is 16 . We will write 1 then a gap and 6.Digital sum of 16 is 7 . So we have totally 8 digits in the answer.and outer digits we  have written and three digits each from either side we have to fillup.For this we will add 7 from either side  and progress Arithmetically . so 1+7 is 8,8+7 is15,  15+7is 22 stop here we have finished 4 digits on this  side .we will add 7 to the other side. 6+7 is 13, 13+7  is 20, 20+7 is 27. Now will add the carry overs and we  get 197...
