Perform two’s complement addition on the following pairs of numbers. In each case, indicate whether an overflow has occurred. a. 1001 1101 + 1111 1110
b. 0111 1110 + 0110 0111
c. 1000 0011 + 1000 0010
d. 1010 1000 + 0010 1100
Homework Answers
The rules for detecting overflow in a two's complement sum are simple:
- If the sum of two positive numbers yields a negative result, the sum has overflowed (sign bit of the result is different from the sign of the operands)
- If the sum of two negative numbers yields a positive result, the sum has overflowed (sign bit of the result is different from the sign of the operands)
- Otherwise, the sum has not overflowed.

Compute 410 – 510 using 4-bit two’s complement addition. You will need to first convert each number into its 4-bit two’s complement code and then perform binary addition (i.e., 410 + (−510)). Provide the 4-bit result and indicate whether two’s complement overflow occurred. Check your work by converting the 4-bit result back to decimal.
