Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

If you were to subtract two 8-bit numbers where the first number is less than the second, derive the Accumulator value and state how the flag status would change.

💡 Hint: Consider what it means in 2's complement for negative results.

Challenge 2 Hard

Design a program that processes three subtractions in sequence, then explain how the flags would be affected after each operation.

💡 Hint: Look for patterns in borrowing as the operation proceeds.
