How Vedic mathematics helps students?
It was a great scholar and philosopher Jagadguru Shankaracharya Swami Bharati Krishna Tirtha (1884 - 1960) who rediscovered the treasure of Vedic mathematics. He, in his book 'Vedic Mathematics', explains the ancient method of calculations which is incredibly easy to understand and apply. These methods are said to be based on 16 sutras or word-formulae which cover all the branches of mathematics, pure and applied.
The system of calculation he introduced in his book is very coherent and systematic. These methods are quite flexible and give us an option of solving most of the arithmetic problems mentally or in a single step 10 to 15 times faster. Though the book was published in 1965, Tirthaji had been propagating this Vedic method of calculation through his lectures and classes long before the book was published.
A few of these methods are applicable only in special cases, but there is always a method which can be applied universally.
For example, I can square a number ending in 5 using a Vedic sutra, Ekadhikena Purvena (meaning 'one more than the previous one). I can apply this method to square numbers ending in 5 only.
Here is how it is done:
To apply this formula, I must know the meaning of the term 'previous'.
If 45 is the number to be squared the 'previous' here is the number before the unit place. Hence 4 is considered as the 'previous' as per the formula.
To get the answer mentally, we have to find the 'one more than the previous one,' (here it is 4 + 1 = 5) and multiply the 10's place by this new number. The result becomes the Left-Hand Side of our answer.
The Right Hand Side is always 25 as the unit place of the number is always 5.
Now, let us find the square of 65.
Multiply 6 by one more than it and get the LHS.
Then write 25 as the RHS.
LHS: 6 x 7 = 42
The square of 65 = 4225
Here is another number that you can try.
Find the square of 125.
LHS: 12 x 13 = 156
The square of 125 is 15625
Vedic mathematics also provide a universally applicable method to find the square of any number, which I do not want to explain here for fear of length of the article.
The benefits of learning Vedic mathematics: There are different opinions among critics about the origin of Vedic mathematics. Some of them find the tag ' Vedic' itself is irrelevant, and it has nothing to do with Vedas.
As a teacher, I have been using this method for about 10 years. I had a very tough time initially to convince people how it works and how it can change the students. I had no examples or standing evidence to prove my claim when I first introduced it in my city. But in a couple of years, I could prove the power of Vedic mathematics and how it works on students with my own students. Since then, I trained thousands of students. I noticed the following changes in almost every student who got trained in Vedic mathematics.
- They improved their mental math skills dramatically. They gained incredible mental math skills and began to get rid of their silly calculation mistakes in no time.
- They began to get rid of finger dependence which made them more confident , faster in calculation, and more accurate.
- They began to develop a very logical approach towards problem-solving.
- They could develop a love for math and began to be very attentive in their math classes.
- They began to be the toppers in their classes and this boosted their confidence level considerably.
- Most students began to compare their answers using Vedic methods and VM served as a fast verification tool for them. It improved their performance in exams.
As J T Glover says, 'the experience of teaching Vedic mathematics methods to children has shown that a high degree of mathematical ability can be attained from an early stage while the subject is enjoyed on its own merits.
Dr. Michael Nelhess, Chairman of Department of Mathematics at M.I.U, Iowa says,"Vedic mathematics is easier to learn, faster to use, and less prone to error than the conventional method.
