The Number & Algebra topic has the lowest number of suggested teaching hours of the five syllabus topics at SL level: 19 hours for SL. However, the number of suggested teaching hours at HL level is significantly higher (39 hours for HL) because of the inclusion of partial fractions, complex numbers, proof and solutions of systems of linear equations.

exercise sets, quizzes & tests for teaching units in Number & Algebra

Changes compared to previous Maths HL-SL syllabusses:
The following syllabus items have been added:
SL 1.2 arithmetic sequences and series: interpretation and prediction where a model is not perfectly arithmetic in real life; students will need to approximate common differences
SL 1.4 financial applications of geometric sequences & series: annual depreciation, calculate value of an investment with interest rate and inflation rate (exam Qs may require technology, including use of GDC financial package)
SL 1.6 simple deductive proof, numerical and algebraic; how to lay out a left-hand side to right-hand side proof; the symbols and notation for equality and identity
HL 1.10 extension of the binomial theorem to fractional and negative indices
HL 1.11 partial fractions; maximum of two distinct linear terms in the denominator, with degree of numerator less than the degree of the denominator
HL 1.15 proof by contradiction; use of a counterexample to show that a statement is not always true
