Hi Mallika,
Thanks for the questions.
1. Finding a digit sum is based on ‘By Addition’, Sutra 7, and casting out 9s is based on Sutra 5: ‘If the Total is the Same it is Zero’.
2. You will see more applications. It can be used in algebra too and for finding a missing digit or coefficient.
3. Patterns are always useful as they lead to more general concepts and ways of extending them and seeing connections with other patterns. It has been said that mathematics is all about the study of patterns. Fot the Vedic Square designs I am not aware of applications other than the fun in generating patterns: someone should look into this 🙂Hi Kana,
For half of 33 you can halve 30 and 3 to get 15 and 1.5. The total is 15 + 1.5 = 16.5.
The answer is given in the answer sheet as 16.5 or 16 and a half, both equally correct.To clarify: A ‘test’ is a ‘quiz’ – two words but with the same meaning on this course.
So there are 9 tests/quizzes, one per week. No other tests/quizzes.Hi Mallika,
Glad you are enjoying the lessons.
The connection between the Sutras and Sanskrit is the Vedic Numerical Code. That code is explained in the last lesson of this course and is explained by Tirthaji in his book. The idea is essentially that a correspondence can be given between Sanskrit consonants and numbers. That way all Sanskrit texts can be read numerically.Hi Savita,
Taking practice question 2, you get 16 for the total of the left-hand column – remember that.
For the next column you find a total of 18, so the 1 in this 18 is taken over to the 16 in the first column, and you get 178 with the 8 appended. Remember 178.
Finally, the right-hand column totals 26, so carry the 2 onto the 178 (to make it 180) and append the 6 to give 1806.I hope this explains it. But there is another method which we will come to later which will allow you to write the digits down one after the other rather than hold the whole thing mentally, which can be a challenge if there are many figures involved.
There’s no general preference Satya. Left to right was prioritised in the first video because most people know how to add from the right. You are right of course that it is easier to start with the units because we are accustomed to that, but most people do find that left to right is often better once you get used to it.
In Vedic maths we say to use the method you prefer. Most people prefer the most efficient method. But you won’t know the most efficient method unless you have had a chance to compare them. So as teachers we need to be fully familiar with all the possibilities and fluent with them. And we don’t say a method is wrong because we prefer a different one. All methods are valid.Hi Shikha,
There are not really hard and fast rules in Vedic maths. We do what we find easiest.
So in this case I would combine 16 and 54 first because that deals with the biggest numbers and leaves the easier additon of 14 til last.
