How to play

Keep the calculations moving.

Solve as many short calculations as you can in 60 seconds. Accuracy carries most of the score, so choose quickly—but do not guess.

Quick Maths is a continuous mental-arithmetic sprint. You have one minute to solve a stream of short calculations, choosing one of four answers each time. There is no fixed question total: careful, fluent solving creates the volume.

How Quick Maths works

The clock starts at 60 seconds and runs across the whole exercise. Each correct or incorrect choice receives immediate feedback, then a new calculation appears. The answer choices are close enough to catch common slips, but every question has exactly one correct option.

Standard and Hard include all four operations. Division questions are created backwards from an integer quotient: the generator chooses a divisor and answer first, then multiplies them to form the number being divided. That means no recurring decimals, rounding rules or ambiguous fractions can interrupt the sprint.

Fresh, reproducible calculations

A seeded generator builds 60 unique expressions before play begins. The same daily seed creates the same ordered bank for everyone, while a practice replay gets a new seed.

What changes between difficulty levels?

Easy concentrates on addition and subtraction with smaller values, alongside some multiplication using familiar times tables. Standard broadens the ranges and adds exact division. Hard uses larger additions and subtractions, multiplication beyond the core 12 times table, and divisions with larger divisors and quotients.

Difficulty does not make the timer shorter. Every level lasts one minute, allowing you to compare repeated attempts at the same level. Results for Easy, Standard and Hard are saved separately because the calculation ranges are not directly comparable.

Mental methods that hold up under time pressure

  1. Bridge through a round number. For 38 + 27, move 2 from 27 to reach 40, then add the remaining 25. Round-number landmarks reduce the amount you need to hold.
  2. Compensate in subtraction. Treat 84 − 29 as 84 − 30 + 1. It is usually easier to reverse a one-point adjustment than perform a long written-style subtraction mentally.
  3. Break multiplication apart. Calculate 14 × 12 as 14 × 10 plus 14 × 2. The same distributive method works when Hard mode goes beyond memorised table facts.
  4. Read division in reverse. For 96 ÷ 8, ask “eight times what makes 96?” This turns division back into a multiplication fact and gives you a quick way to check the answer.

Use the answer choices as a final check, not as the calculation method. Estimation can eliminate an obviously impossible value, but trying every option in turn is slower and increases the chance of accepting a plausible near miss.

How the Quick Maths score is calculated

Accuracy provides 72% of the score. Pace provides 13%, and useful volume—the number of correct calculations completed against the target for that difficulty—provides 15%. This balance gives fluent solvers something to chase without making a single rushed mistake worthwhile.

The pace contribution is adjusted by performance above the 25% accuracy expected from random four-choice selection. At chance accuracy, speed contributes nothing. Volume also counts correct answers rather than attempts, so rapid guessing cannot inflate that part of the result either.

Your Workout Score is a game result for entertainment and personal progress. It is not a measure of intelligence, mathematical potential, neurological health or any medical condition.

Why multiple choice still tests calculation

Four choices make the game comfortable on a phone and permit direct keyboard input. They do not make random selection effective: a guess is expected to be right only one time in four, while accuracy dominates the score and suppresses the pace reward.

The distractors are generated near the true answer and include offsets associated with ordinary slips. A rushed solver might be one away, forget a subtraction adjustment, or confuse a nearby multiplication fact. Actually calculating remains more dependable than scanning for an answer that merely looks familiar.

Common Quick Maths mistakes

Reading faster than you process the operator

Addition and multiplication signs can become visual shorthand during a sprint. Read the operation before the numbers, particularly just after a question changes.

Protecting a streak with a rushed answer

The streak is useful feedback, but accuracy is the larger score component. One deliberate second is often cheaper than ending a run of correct calculations.

Carrying the previous answer forward

Immediate question changes can leave the last value in working memory. Briefly reset your attention to the new operator rather than treating the stream as one connected calculation.

Quick Maths questions

Are there unlimited calculations?

Each attempt prepares a bank of 60 unique questions—far more than a person is expected to answer in one minute. New practice seeds produce new operands, operation order and answer positions, creating a very large supply of valid sprints.

Can division produce decimals?

No. Every division is generated to have a positive whole-number answer, so the game never asks you to infer rounding or decimal precision.

Can I use the keyboard?

Yes. Press 1, 2, 3 or 4 to choose the matching answer card. You can also use arrow keys to move between cards, then Enter or Space to select.

What happens if I leave the tab?

The timer pauses automatically when the page is hidden. You must explicitly resume when you return, preventing an interruption from consuming the rest of the minute.
