The two numbers represent in signed 2's complement form are P = 11101101 and Q = 111001110. If Q subtracted from P, the value obtained in signed 2's complement form is
Answer: Option
Explanation:
P = 11101101 = - 25
Q = 11100110 = - 18
Thus P - Q = - 25 - (- 18) = - 7

The answer is B.
P = 11101101 = -19.
Q = 11100110 = -26.
P - Q = (-19)-(-26) = -19+26 = (7) base 10 = 00000111 base 2.
P = 11101101 = -19.
Q = 11100110 = -26.
P - Q = (-19)-(-26) = -19+26 = (7) base 10 = 00000111 base 2.
