Question

1. Subtract the following questions using 9's
complement and 10's complement.
(a) 3258-82 34.​

Answer 1

Answer:

10's complement of a decimal number can be found by adding 1 to the 9's complement of that decimal number. It is just like 2s compliment in binary number representation. For example, let us take a decimal number 456, 9's complement of this number will be 999-456 which will be 543. Now 10s compliment will be 543+1=544.
