I already gave you the name of the book. Didn't you read my post?

It has no ISBN since it was published in England in 1885.

oeps sorry, my bad. Haven't read your posting properly. Great. I will look into that!

Hope to find it. I love these old books, I have a lot of very old books here.


btw mind to show me

56 x 54=?

Not as a test, but to compare.

It is 0130hrs here. I will have to pass. I had a really big yard sale today that was profitable, but busy.

Now I am looking at pics of nekkid women, playing Majong Titans, and posting on DP.

My apologies.

it's ok.

one more question if I may, do you know the author(s) of the book?

That makes it easier to find.

You can answer later, that's ok with me


Have a good night!

One of the problems with learning Vedic mathematics is that the 'conventional mathenmatics" gets in the way.

Children have no problem at all with this.

So, some people have to 'unlearn' the 'conventional mathematics'.




So, start with a clean slate if you can, and an open mind.

You have really shown your case, but i still prefer 'model c maths.'

well, of course you are free to use whatever you like, hat's simply not up to me.

But what is "model c maths"


And have you tried Vedic mathematics?

You have described this maths form very well, but model c maths works on 'fives and tens.' in model c maths, you estimate where the sum is going, meaning that you can also do multiplication a different way. let me give you an example?

456 x 765. [400] + [50] + [6] * [700] + [60] + [5] = [30 + 250 + 2000] + [36 + 300 + 2400] + [400 * 7 = 4 * 7 * 100= 2800] + [56 * 7 = 560 - [56*3=] 168].

Ok, thank you for showing.

However, I think it is more complicated then Vedic Math,

The 'rule" in VM is that if it isn't very easy it isn't vedic mathematics.


But thanks for sharing.

I think your version is better for multiplication if you learn it from early childhood, and, it is nice to hear of a renovated ancient art. in division is where my version excels.

well, let's see. I don't think so

Give me 1/19 if you don't mind.

With 1 / 19 you would say [100 / 19] = [100 / [20 - 1] ] = [0.05 - 0.001 =] 0.049.

some more decimales please! about 18 please.

and I am sorry to say, but you can check with calculator you are wrong so far.

1/19=0,0526 after rounding 1/19=0.053 NOT 0.049

But your effort is much .appreciated, thank yopu for that.

Now 18 decimals, and not by calculator.

Can you do the sum or not? If you can, and show your working, with this new method you have then it may have legs.

Yes, I will come back to this one as well.
 
indeed..

What are the major benefits of Vedic Mathematics?
• Vedic Mathematics is 10-15 times faster than normal Math.
• Better and Much Improved Academic Performance in school and Instant Results.
• Sharpens your mind, increases mental alertness and intelligence.
• Develops Left & Right Sides of the brains by increasing visualization and concentration abilities. The long lasting result of this activity to develop logical thinking and creativity.
• Vedic Mathematics cultivates an interest for numbers and eliminates the math-phobia present in the students.
• Vedic Math is easy to understand, easy to apply and easy to remember.
• Increases your speed and accuracy.
• Improves memory and boosts self confidence.
• It encourages mental calculations and it is the best exercise for Brain.
• Vedic Math system also gives us a set of checking procedures for independent crosschecking of whatever we do. (“Navashesh” is the in built answer verification system in Vedic Math)
• It acts as a tool for reducing finger counting and scratch work

very well put:

The vedic methods are direct, beautifully interrelated, flexible, much more unified and flowing than traditional mathematics. The methods are truly extraordinary in efficiency and simplicity. Compexly arranged modern mathematical problems can easily be done by simple mental mathematics through these methods.

It is peculiar to arithmetic that once the basic facts are understood any intelligent person can construct the whole science: the science of numbers develops in a totally natural way. Vedic Mathematics uses this very fact. It is based purely on sixteen Sutras, or aphorisms (word formulae). These describe the way the mind naturally works and are therefore a great help in directing the student to the appropriate method of solution. Some examples of sutras are Ekadhikena Purvena Sutra (By one more than the one before) and Urdhwa-tiryagbhyam Sutra (Vertically Crosswise). These are illustrated below.

The most striking feature of the Vedic system is its coherence. Instead of a hotch-potch of unrelated techniques the whole system is beautifully interrelated and unifed, making it extremely easy to understand. This quality makes mathematics easy and enjoyable and encourages innovation. Students can invent their own methods, they are not limited to the one 'correct' method. This leads to more creative, interested and intelligent thinking. Thus, 'difficult' problems or huge sums can often be solved immediately by the Vedic method.

I totally agree:


But the real beauty and effectiveness of
Vedic mathematics cannot be fully appreciated
without actually practising the system.
One can then see that it is perhaps the most
refined and efficient mathematical system
possible

I learnt many new things and it’ll help me to become a very good human being. Vedic Maths should be introduced from Kinder Garden level to become more effective.

Omeed loves the class and all the math “tricks”. We have been very impressed with his multiplication skills.I’ve learned some of the strategies from Omeed and I think it is a fun way to learn math. Thank you

Thank you again SO MUCH for getting Fast Math to HM! My kids both loved it. My 9 yr old was looking forward to it but my 7 yr old was angry at me for signing him up, and was so surprised that he loved it. I am sure there will be more signups in the next few days as word spreads. SO thanks again!

Well, i made my mistake with subtracting four from the nineteen, instead of adding it, hope you don't mind my confused brain?

If we took 1/19 = 0.55, as 100 / 19 = 5 + 5 - from the nineteen five times missing twenty by one? - it is actually 0.55. then to get to the next decimal, we would say that the 0.55 doubled equals 1.1, yes? this means that dividing 1 by nineteen could go up to making the answer, as we are looking for eighteen decimals, you say, [-1.1 * 18] = 19.9 / [19] = 1.6 [remainder 0.02] = 1.69 [remainder 1] = ... [/ 18] = [/ 2] =

where is the anwer with 18 decimals and how you have done that?

ok then,

first I will show how it is done, the technique, called vertically and crosswise:
(there are other ways as well)

image24.jpg

349 x 12.56 ?


we first ignore the ',' ands calculate:

349 x 1256

1 2 5 6

3 4 9
_______ x


we do it from right to left:

1. (6x9)=54 put down '4' carry over the '5'
2. (5x9)+(4x6)=69 + our '5'=74 put down the '4' and carry over the '7'
3. (2x9)+(3x6)+(4x5)=56 and plus our '7'=63, put down the '3' and carry over the '6'
4 (1x9)+(2x4)+(3x5)=32+ our '6'=38, put down the '8' and carry over the '3'
5 (4x1)+(2x3)=10 + our '3'=13 put down '3' and carry over '1'.
6 (1x3)=3 + our '1'=4, so we put down '4'.

and voila!

349 x 1256=438344

Now the correction for the point:

So 349 x 12.56=4383.44 !!!

please note we did actually only very simple multiplications! and all this can be done in one line!


writing it down takes more time then actually doing it.

How to calculate the cube root of 438976?

Well, how is it done in the 'conventional way"?



Vedic Math can do it in 5 seconds! (there is some preparation done.)

That is the same as normal but slightly more complex in explaination and similtaneous working.
