Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Create a version of the calculator that can handle multiple operations (e.g., allow a user to calculate an expression like '5 + 2 * 3'). Explain how you'd manage operator precedence in your design.

💡 Hint: Consider how a simple calculator evaluates expressions based on order.

Challenge 2 Hard

Design an interface for a scientific calculator that includes sine, cosine, and tangent operations. Discuss how you would extend the existing code to include these features.

💡 Hint: Recall how we used buttons for basic arithmetic; similar logic applies to new functions.
