Introduction

If the number is binary, we utilize the complements of 1 and 2. However, if the value is a decimal, we shall use the complement of the nines and tens. The number's 9's complement yields the 10's complement, and the 9's as well as 10's complements can also be calculated using the r's and (r-1complement )'s equations.
