Whereas before, the range of an unsigned 4-bit binary number would have been from 0 to 15, or 0 to F in hexadecimal, we now have a reduced range of -7 to +7. Thus an unsigned binary number does not have a single sign-bit, and therefore can have a larger binary range as the most significant bit (MSB) is just an extra bit or digit rather than a …
