Book 1 · Full Notes Sample: Mathematics, Strand 1 (Numbers)

1.1 Order of Operations (BODMAS)

Key points. Work through Brackets, then Orders (powers and roots), then Division and Multiplication, then Addition and Subtraction.

Worked example. Evaluate 4 + 3 × (10 − 6)²

Brackets: (10 − 6) = 4 Powers: 4² = 16 Multiply: 3 × 16 = 48 Add: 4 + 48 = 52

1.2 LCM and GCD by prime factorisation

Key points. Write each number as a product of primes. The GCD takes the lowest powers of the shared primes; the LCM takes the highest powers of all primes.

Worked example. Find the GCD and LCM of 24 and 36.

24 = 2³ × 3 36 = 2² × 3² GCD = 2² × 3 = 12 LCM = 2³ × 3² = 72

1.3 Fractions

Worked example. Work out 23 + 14

Common denominator 12: 812 + 312 = 1112

Book 2 and Book 3 · Questions with the marking scheme that lives in the separate answer booklet Sample

A shirt costing KSH 800 is discounted by 15%. Find the new price. Discount = 15100 × 800 = KSH 120 → 800 − 120 = KSH 680
Find the compound interest on KSH 20,000 at 10% per annum for 2 years. Amount = 20,000 × (1.1)² = 20,000 × 1.21 = 24,200 → CI = 24,200 − 20,000 = KSH 4,200
A ladder 13 m long rests with its foot 5 m from a wall. How high up does it reach? h² = 13² − 5² = 169 − 25 = 144 → h = √144 = 12 m

Book 2 · Predictive Paper Sample question

Q. Share KSH 7,200 among A, B and C in the ratio 2 : 3 : 4.

Total parts = 2 + 3 + 4 = 9 One part = 7,200 ÷ 9 = 800 A = 2 × 800 = 1,600 B = 3 × 800 = 2,400 C = 4 × 800 = 3,200

That is one strand of one subject.

The full course has every strand of every subject, three books each: full notes, predictive papers in the KNEC 2026 format, and a separate answer booklet. Pick what you need:

✂ New 2026 edition (September): every subject is now Book 1 full notes for the whole cycle, Book 2 predictive papers in the official KNEC paper codes, sections and timings (questions only, with answer sheets to shade), and Book 3 a separate answer booklet that starts on its own divider page. Print Books 1 and 2 for the learner, keep Book 3 to mark.
