Times Tables
The multiplication grid, plus a practice quiz that keeps score.
Chart and quiz
The reference grid runs to 12ร12, with hover highlighting the row and column so the crossing is unmissable, and squares marked along the diagonal. Above it, a quiz: mixed questions or a single table, instant feedback with the correct answer on a miss, and a streak counter that makes five-in-a-row the goal.
The grid is smaller than it looks
Multiplication commutes โ 7ร8 is 8ร7 โ so the 144-cell grid holds only 78 distinct facts, and the ones-and-tens are free. The genuinely useful shortcuts: the 9s count down while their digits sum to 9 (09, 18, 27โฆ), 11s repeat the digit, ร4 is double-double, and ร12 is ร10 plus ร2. What remains is a stubborn handful โ 6ร7, 7ร8, 6ร8 are famously the most-missed facts in schools โ which is exactly what single-table quiz mode is for.
Short daily runs beat weekly marathons for fact fluency. Scores are not stored anywhere, so the quiz stays low-stakes; for longer arithmetic the scientific calculator takes over, and fractions get their own tool with working shown.
Frequently asked questions
What times tables should a child know, and when?
Most curricula expect the 2s, 5s and 10s by age 7-8 and all tables to 12 by 9-10. The single-table quiz mode matches how they are taught: one table at a time.
What are the hardest multiplication facts?
Consistently 6ร7=42, 7ร8=56 and 6ร8=48 โ the middle facts with no pattern shortcut. Drill those three and the whole grid feels easier.
What is the trick for the 9 times table?
The digits always sum to 9 and the tens count up as the units count down: 09, 18, 27, 36โฆ Also finger-counting works: fold the finger you are multiplying by.
Does the quiz go beyond 12?
It asks 2-12, matching school expectation. For arbitrary arithmetic the scientific calculator handles anything.
