Vedic or Galactic Mathematics

[Ryndanangnysen]

Hello all.

I don't known if this is the right thread, but I will see.


Vedic or Galactic Mathematics makes mathematics much more easey efficient and more fun!

(Fron now on I will call this VM=Vedic Mathematics)

It is not only for Arithmatic, but also for algebra, calculus and what have you.


It really makes math so much more enjoable!

The basics is that every mathematical problem can be solved with a 'sutra' !

A kind of a poem.


An example:



Calculate 45 x 45.

Now in VM we use the sutra "One more then the one before"

the one before is '4' and 'one more' must then be the number '5'.

Now we multiplu 4 and 5.


45 x 45= (4x5)/25=2025, that is all!


Some more of this

25 x 25, well, 2 is the 'one before" and "2+1"=3 now we multiply 2 and 3, 2 x3=6

now we get

25 x 25 =(2 x 3)/ 25 this is 625.


Another one:

65 x 65 well that becomes (6 x( 6+1))/25=4225

Now try these:

75 x 75=

35 x 35=


If people are interested here let me know there is so much more!

This sutra only works for numbers with 5 in the unit position (e.g. 05, 15, 25, 35, 45, 55, 65, 75, 85, 95, etc.).

It will work for larger numbers too - but gradually becomes unwieldy → 365² = 36*37*100 + 25 = 133225

Another 'trick' is for numbers the same distance from 'nice numbers' like three away from thirty is 27 and 33: 27 * 33 = 30² - 3² = 900 - 9 = 891
23 * 27 = 25² - 2² = 625 - 4 = 621
44 * 36 = 40² - 4² = 1600 - 16 = 1584
...

 

[Ryndanangnysen]

87 * 99 = 8700 - 87 = 8613

Lots of similar quickies exist.

I know, but this is just for starters, it will go so much deeper.

You are right, but there are a lot of other methods too.

It really is way much better then the conventional math.

yes, and Vedic Math goes much deeper then this! It is called working within a base.

...and for the trick of all tricks: carry a calculator

That is not a trick at all! That is called laziness!

No more Calculators which make the brain lazy. The brain is a mental muscle and needs to be exercised.
Jain predicts that "if we continue to teach children with an over-emphasis of using calculators in the class-room, over a 20 year period, then no doubt, the Global Brain will deteriorate". We pride ourselves that we are a highly intelligent species, but really, are we getting dumber.

Now, can someone show me how to calculate 34 x 11 the conventional way?

Afterwards I will do it the Vedic math way,

 

[Ryndanangnysen]

87 * 99 = 8700 - 87 = 8613

Actually, this one can be done better and moe efficient by Vedic Math!

Afterwards I will do it the Vedic math way,

In decimal system or octal system or hexadecimal system or some other system???

Two digit number xy (which is 10x + y) in decimal system - when x+y<10

xy * 11 = x(x+y)y → 34 * 11 = 3(3+4)4 = 374

Now try these:

75 x 75=

35 x 35=

The good thing is it also works for numbers with more than 2 digits. For example: \(\displaystyle 195^2=\underbrace{380}_{19\times20}\!25\).
