Question 1

What happens when two negative numbers are added in signed arithmetic and the result is interpreted as positive?

  • Overflow occurs
  • Carry occurs
  • No overflow

💡 Hint: Consider the sign bit in the result.

Question 2

The carry flag primarily applies to which type of arithmetic?

  • Signed Arithmetic

Challenge Problems

Push your limits with challenges.

Question 1

You are tasked with designing a system that involves adding two 4-bit signed integers. Explain how you would handle potential overflow in your calculations.

💡 Hint: Consider what conditions will cause the overflow to trigger.

Question 2

In an unsigned arithmetic system, what happens when you add two maximum values (e.g., 15 + 1)? Explain the results and the implications in a larger computation.

💡 Hint: Reflect on the limits set by the number of bits in your system.
