  • Algebraic simplification and rotational symmetry of order 3

  • Currency conversion calculations (Euros to KES and USD) and perpendicular line equations

  • Trigonometric equations (cos(2x + 30 degrees) - sin x = 0) and scale drawing/bearings

  • Relative speed and distance-time calculations for bus and car

  • Calculus differentiation (tangent line equations) and volume-surface area ratios of similar solids

  • Regular polygon interior/exterior angles, linear inequalities, and exponential index equations

  • Position vectors and parallel vector conditions, and 3D triangular prism construction

  Section II:

  • Frequency distribution histograms and graphical median estimation
