UNIT OVERVIEW

This guide helps you prepare for the Grade 10 mid-year mathematics examination. The exam is a two-hour paper worth 100 marks. It tests seven major topics from Terms 1 and 2.

In this revision unit, you will:

• Consolidate algebraic expressions, including factorisation and simplification
• Apply the laws of exponents to complex expressions
• Identify and extend linear and quadratic number patterns
• Solve equations (linear, quadratic, simultaneous) and inequalities
• Apply trigonometric ratios in right-angled triangles
• Sketch and interpret functions (linear, quadratic, hyperbolic, exponential, trigonometric)
• Prove and apply properties of triangles and quadrilaterals

Why these skills matter:

• Financial planning: Exponents and equations help calculate interest and loan repayments.
• Construction: Geometry ensures buildings are structurally sound.
• Technology: Trigonometry helps engineers calculate tower heights and signal coverage.
• Business: Functions model sales data and predict trends.
