Challenge 1.

We can convert bar numbers to normal numbers by applying “one less” and “all from 9 last from 10”.

1. 1(1) = 09 ( one less than 1(in 10s place) is 0 and applying  all from 9 last from 10 to bar 1 will result in 9  )

2. 2(22) = 178 (one less than 2(in 100s place) is 1 and apply all from 9 last from 10 to bar 22  will result in 78)

3. 3(303) = 2697

4.  6(7)8(9) = 5371

5. 77(03)1 = 76971

6. 8(01)9(01) = 799899

Thanks.

You are right Ken. I misread the question. Sorry.

[Basa Mallika Gogulamudi]

Hi,

Thanks for the Q and A video on Vedic Maths. It has deepened my understanding.

In video 1 – lesson 9

Practice 2 & question 2,

5/12 + 5/18 = 25/36

Answer should be 25/36 .

In answers sheet it is mentioned as 25/24.

Thanks,

Mallika

I also noticed it. It has only 4 combinations. This could be a printing mistake.

Hi All,

I want to share my observations.

We can get a remainder on division by 3 using digit sum.

For division by 3 :

As we all know if the digit sum of a given number is 3 or 6 or 9, then the number is divisible by 3 and the remainder will be 0.

If the digit sum of a given number is less than 3, then the digit sum will be the remainder.
Examples :
28 divided by 3 = 9 rem 1, digit sum of 28 is 1 and remainder is also 1.
812 divided by 3 = 270 rem 2, digit sum of 812 is 2 and remainder is also 2.

If the digit sum of a given number is greater than 3, we have to repeatedly subtract 3 from the digit sum until the answer is less than 3 and that answer will be the remainder.
Examples :
25 divided by 3 = 8 rem 1, digit sum of 25 is 7 and if we subtract 3 twice from 7 we get remainder as 1.
98 divided by 3 = 32 rem 2, digit sum of 98 is 8 and if we subtract 3 twice from 8 we get remainder as 2.

This holds good for any number to get a remainder on division by 3 using digit sum.

I am checking if there are any patterns to get a remainder for division by 6 using digit sum but no luck so far.

Thanks.

Hi Satya,

Even though digit sum checking doesn’t spot the error all the time, it is very handy. I have taught this to my 10 year old son. It has spotted errors many times especially in 4 digit by 4 digit multiplications. As 4 digit by 4 digit multiplication is not easy to verify answers using inverse (division) operation.

Thanks.

[Basa Mallika Gogulamudi]

Thanks Ken for the clarification.

Yes, Patterns are very useful in analyzing, predicting, forecasting and in giving projections.

Thanks Ken for all your work and contributions in VM. VM has changed my son’s attitude towards maths. I can’t thank you enough for that.

Hi Ken,

Digit sum concept is really interesting and I would like to explore more.

I have few queries.

1. Are digit sum and casting out 9 based on any Vedic sutra(s)?

2. Do we have any other applications of digit sum other than verifying answers and divisibility checks?

3. Do we have any applications of number patterns and Vedic designs?

Thanks.

Hi. I have already done the quiz. But it still shows Start Quiz under the Quiz 01 section.

[Basa Mallika Gogulamudi]

Hi Ken sir, I thoroughly enjoyed week one videos. Thank you for sharing history about Vedic maths and number system. I particularly like the way you are relating sutras with the brain functionality.

I am curious to know how verse “in the regin of king Kamse famine, pestilence and unsanitary conditions prevailed” translates to Ganita Sutras.

Regards,
Mallika.

Hi Savita,

In sum 2.

1 4 3
3 1 6
8 9 2
1 2 7
3 2 8
__________
17 8(+2) 6
__________

1806 is the final answer.

While working from left to right, 1st column will add up to 16. Before writing down the answer, check the second column if there would be any carry forward. In this case there is a carry forward so instead of writing 16, we write 17. Second column adds up to 18, we have already considered carry forward so we just remember 8 in second column and start adding last column which adds up to 26. 2 is carry forward (8+2 = 10 and 1 in 10 will add to 17). 1806 is the final answer.

We can do the sum 3 also in the same way.

Greetings. Happy new year all.

This is Mallika from Hyderabad, India.

I am a Software Architect with Masters in Computer Science, currently taking a break to take care of my child.

I came across this course while teaching Vedic maths to my 10 year old son. I am excited to be part of this course and learn more about VM.

Thanks to Ken Sir for putting together this great course. I am already enjoying the first week videos.

Regards.
