Textbook chapter 1
Real Numbers
Discover how prime factors describe whole numbers and help solve grouping and repetition problems. Then use a contradiction argument to explain why some square roots cannot be fractions.
Explore chapterTextbook chapter 2
Polynomials
Connect algebraic zeros with x-axis intersections, then use coefficient relationships to check roots and construct quadratic polynomials.
Explore chapterTextbook chapter 3
Pair of Linear Equations in Two Variables
Represent two conditions using two equations. Decide whether both conditions have one common solution, infinitely many or none, and solve practical problems.
Explore chapterTextbook chapter 4
Quadratic Equations
Solve equations whose highest power of the unknown is two, interpret their roots and use a discriminant to decide which real solutions are possible.
Explore chapterTextbook chapter 5
Arithmetic Progressions
Recognise a sequence with a constant change, locate a distant term without listing every term, and add many terms efficiently.

Triangles
Use proportional sides and equal angles to recognise similar triangles. Apply a parallel-line theorem and justify your geometric reasoning.
Explore chapterTextbook chapter 7
Coordinate Geometry
Turn geometric distances and internal ratios into numerical calculations on a coordinate plane. Use results to verify a geometric description.
Explore chapterTextbook chapter 8
Introduction to Trigonometry
Relate an acute angle to side ratios in a right triangle, evaluate standard angles and simplify expressions using identities.
Explore chapterTextbook chapter 9
Some Applications of Trigonometry
Draw a useful right-triangle model to find an inaccessible height or distance from measured angles.
Explore chapterTextbook chapter 10
Circles
Understand tangency and use the two tangent theorems to find unknown lengths and angles.
Explore chapterTextbook chapter 11
Areas Related to Circles
Calculate portions of circular regions and distinguish the curved boundary from a straight chord or radius.
Explore chapterTextbook chapter 12
Surface Areas and Volumes
Model a solid as familiar pieces. Add or subtract volumes, but count only exposed surfaces when calculating an exterior area.

Statistics
Summarise a grouped frequency table using its mean, median and mode, and interpret what each measure tells you.

Probability
Measure the chance of an event in a finite equally likely sample space and check answers using complementary events.
