Which of the following is a true statement about using the 2's complement form to represent negative integers in digital computer data systems? The 2's complement form does not have a sign bit, and mathematical addition using the stored bits will result in the correct sum for positive and negative operands, provided overflow does not occur The 2's complement form is not practical for computer systems using mathematical computations because the numbers would have to be translated to either unsigned or floating point format before the mathematical operation is performed The 2's complement form uses the most significant bit (MSB) as the sign bit. The 2's complement form uses the least significant bit (LSB) as the sign bit
