Mathematics Secondary 5 CST:

Mathematics meets decision-making. You’ll learn to represent linear inequalities as constraints, define the feasible region (polygon of constraints), and apply optimization to find the best solution for real-world problems — whether minimizing cost or maximizing efficiency.

You’ll explore geometry as a language for space and form. Through trigonometric ratios, sine and cosine laws, and area formulas, you’ll solve problems involving equivalent figures and solids — learning how mathematical relationships shape structures in the world around us.

Mathematics can describe networks, routes, and connections. You’ll discover chains, cycles, and types of graphs, then use them to solve optimization problems — from finding the shortest path to understanding the critical path or chromatic number. It’s logic meeting real-world systems.

How do we measure chance? You’ll explore different types of probability and events, understand odds for and against, and calculate mathematical expectation and conditional probability — learning to reason clearly even when outcomes are uncertain.

You’ll study how mathematics helps societies make fair choices. From majority and plurality methods to Condorcet, Borda, elimination, and proportional representation, you’ll see how different systems lead to different results — and what it means to measure fairness.

Money follows mathematical laws. You’ll apply exponents and logarithms to study simple and compound interest, calculate growth and depreciation, and solve financial problems involving time and rate. This is where math becomes a tool for real-life decisions and future planning.
