About this app
Math Guideline is a pocket collection of concise math tips, tricks and guidelines for students. Each tip fits on one screen: a one-line idea, short numbered steps, a worked example and, where it helps, why it works and the mistake to avoid.
98 TIPS IN 11 TOPICS
• Mental Math: multiply by 5, 9, 11, 25 and 99, square numbers ending in 5, multiply numbers near 100, double and halve
• Divisibility Rules: tests for 2 to 12, the rule for 7 and a quick prime check
• Fractions & Percentages: percent shortcuts, percentage change, reverse percentages, comparing and dividing fractions
• Algebra: key identities, solving and checking equations, factoring, the quadratic formula, exponent and log rules
• Geometry: angle sums, Pythagorean triples, special right triangles, areas, circles, volumes and scale factors
• Ratios & Word Problems: ratios, proportions, speed, work, mixtures, unit prices and interest
• Statistics & Probability: averages, outliers, complements, combinations and expected value
• Estimate & Check: estimation, last-digit checks, casting out nines, units and parity
• Problem Solving: Pólya's four steps, working backwards, patterns, pairing and tables
• Exam & Study Strategy: time budgets, back-solving multiple choice, error logs and spaced practice
• Common Mistakes: the traps that cost marks, from (a + b)² to percentage points
