fast calculation in maths
calculation of simple arithmatic than usual method.
like for example:
if u want to multiply 99971 by 99988 without using pen/paper
99971
*99988
-------- 100 - 71=29
100 - 88=12
then 29* 12= 348 ,so put 348 at end then since the numbers are five digit make it five digit like 00348.then multiply lesser number (12) unit placenumber (2) ( 2*29=58)
then add (58+1)
put as 5400348
then the three numbers which are similar 999 before what we got from the above process like 9995900348.
now u get the value without pen and paper aith just ur brain faster than usual conventional method
.
there are several methods just u can try urself
