MathFormulaQuiz

You know the formula. Then the problem appears and you are stuck. Most mistakes in maths come down to two questions: which formula applies, and what goes where. Math Formulas & Quiz puts a formula reference and a problem set in one app, so you can look a formula up, practise it straight away, and jump back to it the moment you get something wrong. ■ 226 formulas, algebra to calculus Expansion and factoring, quadratic functions, sets and logic, trigonometry, data analysis, counting and probability, geometry, integers, proofs, complex numbers, coordinate geometry, trigonometric functions, exponentials and logarithms, differentiation and integration, sequences, and statistical inference. Sixteen units, organised by subject, then unit, then formula. The course follows the Japanese high-school curriculum (Math I, A, II and B), and every formula, problem and explanation is fully available in English. ■ An explanation and an example for every formula Each formula comes with a short explanation of what it means and when to use it, including the slips students make most often. All 226 have a worked example with the substitution and every step shown. 95 formulas also list the conditions they need, and 20 geometry formulas include a diagram. ■ 2,000+ multiple-choice problems 2,087 problems, written for specific formulas, so you can drill exactly the one you need. Choose the range: everything, a subject, a unit, a single formula, your favourites, or your weakest formulas. Sets are 10, 20 or 30 questions. ■ Step-by-step solutions The solution opens as soon as you answer. Every calculation follows the same order: the formula, what to substitute, the working, the answer. Every step shown was checked by computer algebra. From a solution you can open the formula it used, and from a formula you can go straight to its problems. ■ See where you are weak Overall accuracy, accuracy by subject and by unit, best streak, and recent sets. Units are listed from lowest accuracy up, so you know what to review next. Pick "Weakest" to practise your three lowest-scoring units. ■ 27 achievements Sets played, lifetime correct answers, streaks, perfect sets, accuracy, correct answers per subject, consecutive days and formulas viewed give you the next goal to aim for. ■ Handy tools - Search by formula or unit name - Save favourites and quiz yourself on them - A built-in normal distribution table - Adjustable formula text size - Two colour themes, Paper and Night - Sound and haptics you can switch off - One reminder a day, at 7:30 AM or 7:30 PM on alternating days (you can turn it off) ■ Who it is for - High-school students preparing for tests and entrance exams - Anyone who wants to check a formula with a worked example - Adults returning to maths ■ No ads, works offline There are no ads, no account and no sign-in.
