Twenty division problems on one board, every single one of them exact — the puzzles are built backward from the answer, so "72 ÷ 8" style questions always land on a clean whole number. No remainders, no decimals, ever.
Divisors stay between 2 and 9, so this is really inverse times tables plus a bit of stretch: quotients run up to 30, which means dividends can reach 270. It's a great follow-up to the multiplication board — same facts, opposite direction, which is exactly how division fluency is built.
How to play
All 20 quotients are visible at once; solve them in any order.
Type the answer — an exact match with an unsolved problem commits on the spot, no Enter needed.
Enter on a wrong number just shakes and clears the box; there's no penalty.
The clock counts up from your first keystroke — beat your previous time rather than a deadline.
"Reveal answers" after the run shows anything you left blank.
What counts in this quiz
20 problems per run; divisors range from 2 to 9 and answers from 2 to 30.
Every dividend is constructed as divisor × answer, so division always comes out exact.
Answers are unique per board — each typed number matches exactly one problem.
What's not included — and why
No remainders, fractions, or decimals — every problem is generated to divide cleanly, because typing "8 r 3" into a speed quiz is nobody's idea of fun.
No division by 1 (trivial) and never by 0 (undefined) — divisors start at 2.
Good to know
The ÷ symbol (the "obelus") was popularized by Johann Rahn in 1659 — and the international ISO standard for math notation now recommends against using it at all.
Division by zero isn't infinity — it's undefined, because no number times 0 can give you back a nonzero dividend.
Quick check: a number is divisible by 3 exactly when its digits sum to a multiple of 3.
