In 1998 Mr. Pradeep Kumar(alumnus IIM Bangalore started working on Vedic Math, it was a little known subject and everybody who came to know about his decision discouraged him. At that point of time he felt that the Vedic math is incoherent. Later he realized Vedic math needed to be arranged in a systematic way so that trainers can teach it and drive results. Today Magical Methods has made Vedic Math teaching a systematic one which delivers result.
Finding Square of an adjacent number
We generally know the square of 30, 40, 50, 60 etc. but if we are required to calculate the square of 31 or say 61 we will scribble on paper and try to find out the answer to the question. Through Vedic math formula is simple and the application is simpler.
Say you know 602 = 3600
Then 612 will be given by the following
612 = 602 + (60 + 61) = 3600 + 121 = 3721
Or Say you know 252 = 625 then
262 = 625 + (25 + 26) = 676
Like above we can find the square of a number that is one less than the number whose square is known. Likewise we can find the square of a number that is one less than the number whose square is known.
Say you know 602 = 3600
Then 592 will be given by the following
592 = 602 – (60 + 59) = 3600 – 119 = 3481
Or Say you know 252 = 625 then
242 = 625 – (25 + 24) = 576
Finding Square of a number ending with 5
After learning this we are able to find the square of any number ending with 5.
Say you want to find square of 115
Then 1152 will be given by the following
Multiply 5 by 5 and put 25 as your right part of the answer.
Multiply 11 by the next higher digit i.e 12 and put 132 as your left part of the answer.
Answer is 13225
Say you want to find square of 85
Then 852 will be given by the following
Multiply 5 by 5 and put 25 as your right part of the answer.
Multiply 8 by the next higher digit i.e 9 and put 72 as your left part of the answer.
Answer is 7225
Multiplication of two numbers that differ by 2
Say you want to multiply 18*20
Then the solution will be given by the following
When two numbers differ by 2, their product is always the square of the number in between these numbers minus 1
18*20 = 19 * 19 – 1
Answer is 360
How to perform instant subtraction
Say you want to subtract 357 from 1000
Then the solution will be given by the following
We subtract each figure in 357 from 9 and the last figure from 10
9-3=6
9-5=4
10-7=3
Answer is 643
Say you want to subtract 85 from 1000
Then the solution will be given by the following
We take 85 as 085 and
9-0=9
9-8=1
10-5=5
Answer is 915
