Mathematics for the JAMB Exam
JAMB Mathematics is required for science, engineering, and social science university admissions. It tests number theory (sets, indices, surds), algebra, geometry, trigonometry, and introductory statistics. The CBT format means all 40 questions are multiple choice, rewarding fast and accurate calculation.

Common failure modes
These are the patterns that cause most candidates to lose marks on this topic. Recognising them in advance is half the work.
- !Spending too long on difficult questions and not finishing all 40 in the allotted time
- !Calculation errors without a calculator — JAMB Mathematics is non-calculator
- !Misapplying the modular arithmetic rules in number base questions
Study tips
- 1Solve 10–15 JAMB past-paper questions daily — the question types are highly repetitive across years.
- 2Master number base conversions (binary, octal, hexadecimal) — they appear in every JAMB Maths paper.
- 3For geometry, memorize the standard angle theorems and the properties of quadrilaterals.

Convert 110₂ (binary) to base 10:
- A4
- B5
- C6Correct
- D8
Why this answer?
110₂ = 1×2² + 1×2¹ + 0×2⁰ = 4 + 2 + 0 = 6₁₀.

If log₁₀ 2 = 0.3010, find log₁₀ 8:
- A0.6020
- B0.9030Correct
- C1.2040
- D2.408
Why this answer?
log₁₀ 8 = log₁₀ 2³ = 3 × log₁₀ 2 = 3 × 0.3010 = 0.9030.
