Many processors provide logic for performing arithmetic on packed decimal numbers.Although the rules for decimal arithmetic are similar to those for binary operations, the decimalresults may require some corrections to the individual digits if binary logic is used.Consider the decimal addition of two unsigned numbers. If each number consists of Ndigits, then there are 4N bits in each number. The two numbers are to be added using a binaryadder. Suggest a simple rule for correcting the result. Perform addition in this fashion on thenumbers 1698 and 1786.
