Division by Nikhilam, 18 mathematics tricks and fun  In the current system, We need to use trial digits when dividing with big divisors.in the vedic system We can  add or subtract for division which makes it easy. Here there are 4 methods of which argumental division  I am omitting since it is good for algebraical divisions  and not for arithmetical computations. (1)Nikhilam method used for big numbers,  (2)paravartya method for smaller digits.Best of all  these and (3)quick one is Straight Division. Nikhilam Sutra is used as said earlier when divisor is  with bigger digits like 6,7,8,90.we should find the complement of this and divide.  Here we have 3 examples. First 2 are two digit  numbers to be divided by 9.The third one is three digit dividend. In all these divisor is 9.The complement  of 9 is 1. We will write this as 9/1, as shown.Now We should count the digits in the divisor and that much  digits we should count...
