Question 1

How does my progress save in Speed Math?

Accepted Answer

Your best streak per (operations, range, option count) combination is stored locally in your browser, so changing the range or enabling a new operation gives you a fresh score to chase rather than overwriting the old one. Sign in to sync the same progress across phone, tablet, and desktop.

Question 2

What operations does Speed Math cover?

Accepted Answer

Addition, subtraction, multiplication, division, squares (n²), and square roots. Any combination can be enabled at once · drill a single operation, mix two, or rotate through all six. Number ranges run from 0-10 up to 0-1,000,000 so the same game scales from early-school practice to mental-math sport.

Question 3

Is it suitable for kids?

Accepted Answer

Yes. Set the 0-10 or 0-20 range and stick to addition / subtraction for early arithmetic; add multiplication and squares for times-table drilling around age 8-10. Wrong answers end the round but never punish past performance, so kids can restart without losing prior progress.

Question 4

How is the score calculated?

Accepted Answer

Your score is the length of the current streak of correct answers. One wrong pick ends the streak and the best streak per setup is saved locally. There is no point penalty for retrying · only the streak resets.

Question 5

How do I pick harder problems if it feels too easy?

Accepted Answer

Three knobs make the game harder. Widen the number range (the 0-100,000 range forces real mental tricks). Raise the answer-option count from 2 to 10 (more discriminate options). And enable squares or division, which most people find harder than addition · then leave them mixed in with easier operations so you can't coast on the rhythm of one rule.

Question 6

Can I play offline?

Accepted Answer

Yes. PlayMemorize is a Progressive Web App. Install once and Speed Math plays without an internet connection.
