No need to convert to base 10. Just subtract the highest digit possible in that base from each digit and then add 1 to get r's complement. r's complement of a number = $r^{n}-y$ Reference on complementary number system: https://en.wikipedia.org/wiki/Method_of_complements#Numeric_complements 1 votes 1 votes air1ankit commented Feb 3, 2018 reply Follow Share 7777-6250 = 1527 + 1 = (1530)8 is it correct ?? 0 votes 0 votes anchitjindal07 commented May 18, 2018 reply Follow Share @air1ankit Yes the addition is correct as it is in base 8, not base 10 0 votes 0 votes Please log in or register to add a comment.
