Vedic Maths--> u can calculate in a jiffy!!

[prasadkowli80]

hey friends,
U might have or mostly not have known the name
"Vedic Maths ".

its a way of fast calculation ..its just magical.
well i will show u some examples how r they carried out by Vedic Maths. -->


I] Multiplying numbers just over 100.

103 x 104 = 10712
The answer is in two parts: 107 and 12,
107 is just 103 + 4 (or 104 + 3),
and 12 is just 3 x 4.

Similarly 107 x 106 = 11342
107 + 6 = 113 and 7 x 6 = 42


II]Method for multiplying numbers where the first figures are the same and the last figures add up to 10.

32 x 38 = 1216
Both numbers here start with 3 and the last
figures (2 and 8) add up to 10.

So we just multiply 3 by 4 (the next number up)
to get 12 for the first part of the answer.

And we multiply the last figures: 2 x 8 = 16 to
get the last part of the answer.

Practise some:

1) 43 x 47
2) 24 x 26
3) 62 x 68
4) 17 x 13
5) 59 x 51
6) 77 x 73

well..these were only some methods of fast multiplication.

well..if u r really interested in knowing more...U can mail me at
[email protected] !!
I would definerely giveu some articles and also teach U !!

till then bye

34*45=30*45+30*5

30*45 = 45*3*10


5836*8844=
11672*4422=
23344*2211=


x*x=(x - a) * (x + a) + a^2

These are just a few of the things I taught myself in Junior High... almost everyone else in my class needs a calculator for 5*8(someone answered 45 to that LOL!)
5*8 = 10 * 8 / 2

i dont know if you have an error on the first example alkatran

30 * 45 = 1350
34 * 45 + 30 * 5 = 1680

prasadkowli, thats cool, i read something like that but it only
talked about squaring numbers that ended with 5

25 × 25 = 625 2 × 3 = 6 25 <-- but you always add 25 @ the end

35 × 35 = 1225 3 × 4 = 12 25 <-- same

i was going to post this, but then i noticed that its the same thing
from youros

I think that website, "Dr. Math" or something along those lines has a whole bunch of multiplication and division shortcuts.
