Mathematics Quiz
From quick arithmetic to algebra and geometry, challenge your problem-solving skills with 50 timed maths questions.
Why Maths Quizzes Are Uniquely Valuable
Unlike other quiz categories where you recall facts, maths quizzes require you to actively compute answers under time pressure. This makes them one of the best ways to build mental arithmetic speed, reinforce mathematical concepts, and develop the kind of quick problem-solving ability that is valuable in exams, careers, and daily life.
Our Mathematics category at QuizOxa covers a broad range of topics — from basic arithmetic that younger learners can enjoy, to algebra, geometry, and probability questions that challenge even confident mathematicians. Every question includes a step-by-step explanation, so even if you get the answer wrong, you learn the method.
What This Quiz Covers
- Arithmetic & Number Theory — Multiplication, division, squares, square roots, and powers of 2. Mental maths shortcuts that save time.
- Algebra — Solving for x, simplifying expressions, and understanding variable equations.
- Geometry — Areas of rectangles, circles, and triangles. Perimeters, angles in polygons, and shape properties.
- Fractions & Percentages — Converting between fractions, decimals, and percentages. Discount calculations and ratio problems.
- Prime Numbers & Sequences — Identifying primes, recognising geometric and arithmetic sequences, and finding the next term.
- Statistics Basics — Mean, median, probability, and data interpretation.
- Mental Maths — Speed tricks for multiplication, division, and percentage calculations without a calculator.
Difficulty Levels
- 😊 Easy (30 seconds, 100 pts) — Straightforward calculations: 7 × 8, 25% of 200, square of 12, and basic geometry formulas.
- 🔥 Medium (20 seconds, 150 pts) — Multi-step problems: area of circles, LCM/HCF, factorials, and discount calculations.
- 💀 Hard (15 seconds, 200 pts) — Complex problems under extreme time pressure: probability, power rules (2³ × 2²), converting decimals to fractions, and sequence patterns.
Sample Questions
Q1. 15 × 15 = ?
✅ Answer: 225
Quick method: (10+5)² = 100 + 100 + 25 = 225. Squaring numbers ending in 5 follows a neat pattern.
Q2. What is 25% of 200?
✅ Answer: 50
25% = one quarter. 200 ÷ 4 = 50. Percentage calculations are among the most tested maths skills.
Q3. What is π (pi) approximately?
✅ Answer: 3.14159
Pi is the ratio of a circle's circumference to its diameter. It is an irrational number — its digits never end or repeat.
Q4. Area of a circle with radius 7cm (π=22/7)?
✅ Answer: 154 cm²
Area = πr² = (22/7) × 49 = 154 cm². This formula is essential for geometry questions.
Q5. What is 5! (5 factorial)?
✅ Answer: 120
5! = 5 × 4 × 3 × 2 × 1 = 120. Factorials are used in permutations and probability calculations.
Tips for Solving Maths Questions Faster
- Memorise key squares — Know squares from 1² to 20² instantly. This saves seconds on many questions.
- Learn percentage shortcuts — 10% = move decimal one place. 25% = divide by 4. 50% = halve. These are faster than multiplying.
- Break complex problems down — 99 × 11 = (100-1) × 11 = 1100 - 11 = 1089. Simplification is key.
- Know your formulas — Area of circle = πr². Perimeter of square = 4 × side. These appear repeatedly.
- Practice under time pressure — Hard mode gives you only 15 seconds. Regular practice builds speed.
