  These notes provide exhaustive, step-by-step coverage across key learning strands, sub-strands, and core competencies:

  • Strand 1.0: Numbers and Algebra:
    • Sub-Strand 1.1: Quadratic Expressions and Equations: Standard form classification; expansion of algebraic brackets; factorisation methods including greatest common factors, monic and non-monic grouping, and difference of two perfect squares; solving quadratic equations using factorisation, completing the square, and the quadratic formula; discriminant interpretation for real roots; Cartesian parabola characteristics (vertex, y-intercept, x-intercepts, axis of symmetry); and contextual geometric area modeling.
    • Sub-Strand 1.2: Irrational Numbers: Structural distinctions between rational numbers (terminating and recurring decimals) and irrational numbers (non-terminating, non-recurring decimals); surd definition and radical simplification by extracting square factors; algebraic operations involving like surds; and systematic rationalisation of monomial and binomial denominators using conjugates.
    • Sub-Strand 1.3: Linear Inequalities: Properties of inequality symbols, preservation and reversal of inequality signs under arithmetic operations, solving one-variable linear and compound inequalities, number line representations with open and solid endpoint conventions, and graphing two-variable linear inequalities using solid/dashed boundary lines and test-point region shading.
    • Sub-Strand 1.4: Logarithms II: Conceptual foundation of logarithms as powers, equivalence between exponential and logarithmic forms, application of core logarithmic laws (multiplication to addition, division to subtraction, power to coefficient), solving logarithmic and exponential equations, checking argument domain restrictions, and change-of-base applications.
    • Sub-Strand 1.5: Formulae and Variation: Algebraic transposition to change the subject of formulae containing rational expressions and radical powers; mathematical modeling of direct variation, inverse variation, joint variation, and partial variation; determining constants of proportionality; and interpreting linear and hyperbolic variation graphs.
    • Sub-Strand 1.6: Sequences and Series: Sequence term definition and general rules; arithmetic progressions (first term, common difference, general nth term, summation of first n terms using endpoint and difference formulae, paired-sum models); geometric progressions (common ratio, nth-term formula, finite geometric series summation); and real-world compound financial modeling.
    • Sub-Strand 1.7: Matrices (I): Matrix notation, dimensions, and element indexing; classification of special matrices (row, column, square, zero, diagonal, and identity); scalar multiplication, matrix addition and subtraction rules; row-by-column matrix multiplication algorithms and dimension compatibility; determinant calculation for 2x2 matrices, matrix inversion, and solving two-variable linear simultaneous equations using matrix inverses.
