For signed binary numbers the most significant bit (MSB) is used as the sign bit. If the sign bit is “0”, this means the number is positive in value. If the sign bit is “1”, then the number is negative in value. In two’s complement, the positive numbers are exactly the same as before for unsigned binary numbers. What is the following signed 2’s complement( 1’s complement +0b1) binary number in decimal, 0b110101101?
