Question

Convert the following decimal numbers to 6-bit two's complement binary number and add them. Keep result in binary form. Enter yes/no for any overflows (overflows only, not carried bits).

16 + 9 .............. Overflow?...................

27 + 31 .............. Overflow?.......................

(-4) + 19 .............. Overflow? ........................

3 + (-32) ............ Overflow? ........................

(-16) + (-9) ............... Overflow? ..............................

(-27) + (-31) ................ Overflow? ...........................................

Answer 1

Note:

Negative numbers are represented in 2's complement form

2's complement=1's complement+1

Where 1's Complement is nothing but just reversing bits from 0's to 1's and 1's to 0's
