Solution

The arithmetic expression that would potentially cause an overflow problem in a 16-bit two's-complement representation is "-32,000 + 32,768 + 32,000".

Here's why:

  1. "-16,384 + 16,384": The result of this operation is 0, which is within the range of a 16-bit two's-complement representation (-32,768 to 32,767).

  2. "-32,000 + 32,768 + 32,000": The operation is completed from left to right. So, first, "-32,000 + 32,768" is calculated, which gives 768. Then, 768 is added to 32,000, which gives 32,768. This is outside the range of a 16-bit two's-complement representation, hence it would cause an overflow.

  3. "-32,000 + 32,000 - 32,768": The operation is completed from left to right. So, first, "-32,000 + 32,000" is calculated, which gives 0. Then, 0 is subtracted from 32,768, which gives -32,768. This is within the range of a 16-bit two's-complement representation.

  4. "25,000 – (-7,767)": The result of this operation is 32,767, which is within the range of a 16-bit two's-complement representation.
