Challenge Problems

Push your limits with challenges.

Question 1

You have a dividend of 28 and a divisor of 5. Use both the restoring and non-restoring algorithms to compute the quotient and remainder. Show each step.

💡 Hint: Remember to carefully track each subtraction and check your remainder!

Question 2

Critically analyze an application where restoring division may be preferable to non-restoring division despite the latter's efficiency. Provide your reasoning.

💡 Hint: Think about when clarity outweighs speed.
