A) negative numbers are represented in 2's- complement form and a means is provided to take the 2's- complement of the minuend in subtraction problems.
B) negative numbers are represented in 2's- complement form and a means is provided to take the 2's- complement of the subtrahend in subtraction operations.
C) negative numbers are represented in 2's- complement form and a means is provided for taking the 2's- complement of the minuend and the subtrahend in subtraction problems.
D) positive numbers are represented in 2's- complement form and a means is provided to take the 2's- complement of the minuend in subtraction problems.

Question

Quizplus · Accepted Answer

In subtraction operations using signed binary numbers, representing negative numbers in 2's-complement form allows for direct subtraction by taking the 2's-complement of the subtrahend and adding it to the minuend. This process effectively turns subtraction into addition, which can be easily handled by parallel full-adders.
