One advantage of using the 2's-complement system to represent signed numbers is:
 
  A) division can be accomplished by performing multiplication.
  B) subtraction can be accomplished by performing addition.
  C) addition can be accomplished by performing subtraction.
  D) multiplication can be accomplished by performing division.

Question 2

What is the difference between the sign-magnitude and 2's-complement systems of representing signed binary numbers?
 
  A) In the 2's-complement system, all positive numbers are entered in the 2's-complement form preceded by 0 to indicate the sign and all negative numbers are entered in straight binary format preceded by a 1 to indicate the sign. The sign-magnitude system requires that positive and negative numbers be entered in straight binary form preceded by a 0 or 1 to indicate the proper sign.
  B) In the 2's complement system all numbers, regardless of signs, are entered in the 2's-complement preceded by a 1 or 0 to denote sign. In the sign-magnitude method, the magnitude bits represent the true binary value and the bit preceding the MSB represents the sign of the following bits.
  C) In the signed-magnitude system all numbers, regardless of their sign, are in straight binary format preceded by a 0 or 1 to denote the sign. In the 2's complement system, the negative numbers are entered in the 2's-complement form preceded by a 1 to acknowledge a negative number whereas positive numbers are entered in straight binary format preceded by a 0 to indicate the sign.
  D) In the sign-magnitude system all numbers, regardless of their sign, are in the 2's-complement form preceded by a 0 or 1 to indicate their sign. On the other hand, the 2's-complement system requires the sign-magnitude bits be in straight binary format preceded by a 0 or 1 to denote the proper sign.
