1Express 84 as a product of its prime factors.
A.2 × 3 × 7
B.2^2 × 21
C.2^2 × 3 × 7
D.2 × 42
Explanation: Dividing repeatedly: 84/2=42, 42/2=21, 21/3=7, 7/7=1. This gives two 2s, one 3 and one 7, so 84 = 2^2 × 3 × 7.
2Find the highest common factor (HCF) of 36 and 48.
A.6
B.12
C.18
D.24
Explanation: 36 = 2^2 × 3^2 and 48 = 2^4 × 3. The HCF takes the lowest power of each common prime: 2^2 × 3 = 12.
3Find the lowest common multiple (LCM) of 8 and 12.
A.96
B.48
C.4
D.24
Explanation: 8 = 2^3 and 12 = 2^2 × 3. The LCM takes the highest power of each prime: 2^3 × 3 = 24.
4Evaluate -7 + 12 - (-3).
A.2
B.8
C.-2
D.22
Explanation: Subtracting a negative is the same as adding: -7 + 12 + 3 = 8.
5Write 0.0045 in standard form.
A.4.5 × 10^3
B.4.5 × 10^-3
C.45 × 10^-4
D.4.5 × 10^-2
Explanation: Standard form is A × 10^n with 1 ≤ A < 10. Moving the decimal point 3 places right gives 4.5, so 0.0045 = 4.5 × 10^-3.
6Evaluate (3 × 10^4) × (2 × 10^3), giving your answer in standard form.
A.5 × 10^7
B.6 × 10^12
C.6 × 10^7
D.6 × 10^6
Explanation: Multiply the numbers: 3 × 2 = 6. Add the indices: 10^4 × 10^3 = 10^7. The result is 6 × 10^7.
7Simplify 5^3 × 5^2.
A.5^6
B.5^5
C.25^5
D.10^5
Explanation: When multiplying powers with the same base, add the indices: 5^3 × 5^2 = 5^(3+2) = 5^5.
8Evaluate 2^-3.
A.-8
B.-6
C.1/8
D.1/6
Explanation: A negative index means the reciprocal: 2^-3 = 1/2^3 = 1/8.
9A map has a scale of 1 : 50 000. Two towns are 6 cm apart on the map. Find the actual distance in km.
A.300 km
B.30 km
C.0.3 km
D.3 km
Explanation: Actual distance = 6 × 50 000 = 300 000 cm. Converting: 300 000 cm = 3000 m = 3 km.
10Divide $120 between A and B in the ratio 3 : 5. How much does B receive?
A.$45
B.$60
C.$75
D.$40
Explanation: Total parts = 3 + 5 = 8, so one part = $120/8 = $15. B receives 5 parts = 5 × $15 = $75.

About the N(A)-Level Mathematics Exam

The N(A)-Level Mathematics examination (Syllabus 4045) is the Singapore-Cambridge GCE Normal (Academic) Level mathematics paper taken by Secondary 4 Normal (Academic) students. Content is organised into three strands: Number and Algebra, Geometry and Measurement, and Statistics and Probability. The exam has two compulsory papers, each 2 hours: Paper 1 (about 23 short-answer questions, 70 marks) and Paper 2 (90 marks, with Section A including a real-world problem and Section B). An approved calculator may be used in both papers, and results are graded 1 to 5. The syllabus is less advanced than O-Level Elementary Mathematics, and strong N(A) candidates may be offered the higher O-Level Maths syllabus.

N(A)-Level Mathematics Study Tips from Top Performers

1Master the basics first: prime factorisation, HCF/LCM, fractions, percentages and ratio underpin many Paper 1 questions.
2Always show full working; method marks are awarded even when the final answer is wrong.
3Practise the real-world problem at the end of Paper 2 Section A, which often blends finance, rates and data interpretation.
4Learn the formula sheet but memorise area, volume and trigonometry formulae you use most so you save time.
5Use your approved calculator efficiently and round only at the final step, keeping the unrounded value in memory.
6Drill past-year SEAB papers under timed conditions, 2 hours per paper, to build speed and accuracy.
