🔍 Introduction: Why SageMath?
Whether you're calculating grades for students or tracking financial growth for retirement, SageMath simplifies the math while sharpening your coding skills. Imagine automating tasks you once did manually—saving time, reducing errors, and gaining confidence in both math and programming.
Let’s explore five hands-on exercises using SageMath, each with real-life relevance, visual support, and engaging challenges to level up your skills.
🧪 Exercise 1: Max Absolute Value Finder
💡 Scenario
Need to quickly find the furthest number from zero in a list of values—whether in physics data, budget projections, or error margins?

🧰 Debug Tip
🚨 Edge Case: What happens when all numbers are zero or identical? Test with [-3, -3, -3].
🔄 Try This!
-
Modify the function to accept dynamic user input via list(map(int, input().split())).
-
Reflection Prompt: How would you handle floating-point values or negative-only sequences?
💰 Exercise 2: Investment Calculator with Interest
💡 Scenario
Track compounded investments over years—and expand it to simulate monthly deposits for recurring savings.
🔁 Sample Expansion Code
🧰 Debug Tip
⚠️ Power Check: Don’t use ^ for exponentiation in SageMath. Use ** instead.

📍 Exercise 5: Point Classification
💡 Scenario
Determine the quadrant of a 2D point—or extend it to 3D classification in space (e.g., robotics, navigation).
🧪 Quiz
📍 What will classify_point(-4, 0) return?
🧰 Debug Tip
⚠️ Test edge cases like x = 0 and very large y to ensure logical accuracy.
🧠 Advanced Challenge
🗺️ Bonus Visual
Plot test points like (5, -5), (0, 0) and color-code them by quadrant.
