Question

Suppose you are working with 4 bit 2's complement signed numbers. Which pairs of numbers, if added, will produce the wrong result (overflow).

Answer 1

-6 and -3

Step-by-step explanation:

4 bit 2's complement can represent numbers between -8 and +7.

Overflow can occur if the result is greater than 7 or less than -8.

If two numbers with the same sign positive or negative are added and the result gives an opposite sign,an overflow has occurred
