Signed Magnitude Examples (8 bits)
-5 = % 1 0000101 = $ 85+5 = % 0 0000101 = $ 05+127 = % 0 1111111 = $ 7F -127 = % 1 1111111 = $ FF+ 0 = % 0 0000000 = $ 00 - 0 = % 1 0000000 = % 80
For 8 bits, can represent the signed integers -127 to +127.
For N bits, can represent the signed integers
-2(N-1) - 1 to + 2(N-1) - 1
