Note:This is not a question This is my first tutorial and i begin with some maths tricks that i hope you all will like ..do provide your feedback! thanks! P.S. more tutorials coming :)
Square of numbers near to 100 ------------------------- Let me explain this trick by taking examples 96^2 :- First calculate 100-96, it is 4 so 96^2 = (96-4)----4^2 = 9216 similarly 106^2 :- First calculate 106-100, it is 6 so 106^2 = (106+6)----6^2 = 11236 Now , An other case arises 110^2 = (110+10)----100 = (120+1)----00 = 12100 similarly 89^2 = (89-11)----121 = (78+1)----21 = 7921
not only for hundred , it is for every no. near 10,100,1000,10000,etc.
@shubham.bagrecha indeed we can extend to 100,1000,....etc using the similiar method
Can u explain why it works..
even i didn't get this : 96^2 = (96-4)----4^2 = 9216
96-4=92 4^2=16 So, it becomes 9216
Like adding strings
|dw:1349177633165:dw||dw:1349177692486:dw|
I think now I get it how it works...
81^2 = 81-19---19^2 =62|361 = 6561 because 3 is carried over.....
now i remember this, i had learned this years ago, under the topic speed calculation/vedic maths
:) yes these methods are a part of Indian vedic maths !!!
