576 squares, 209 answers
Five answers tie as the most common, with 8 squares each: 24, 48, 60, 72 and 120. All but 60 sit in the tinted row. Count a fact and its turnaround once and the chart holds 300 facts, 222 more than a 12 by 12 chart.
Sizes 22 and 23 on the same page
Under the chart, Chart size redraws the grid as 1 to 22 or 1 to 23 and tints the new last row. The 22 row is the 11 row doubled: 11 × 7 = 77, so 22 × 7 = 154. 23 is prime, so every answer in its row sits only in row 23 and column 23. Tap any 168 to light every 168.
- Treat 24 as 25 − 1. 24 × 8 is 200 − 8 = 192, and 24 × 16 is 400 − 16 = 384.
- The 12 row doubled gives the 24 row: 12 × 9 = 108, so 24 × 9 = 216.
- 24 is two dozen, so 24 × 6 = 144 is a gross and 24 × 12 = 288 is two gross.
Questions and answers
What is a multiplication chart of 24 good for?
Hours. The tinted row is the 24 times table, so 24 × 5 = 120 is the hours in 5 days and 24 × 14 = 336 the hours in 2 weeks. 24 × 15 = 360 also matches the degrees in a full turn.
Is there a 22 multiplication chart or a 23 multiplication chart here?
Yes, both. Pick 1 to 22 or 1 to 23 under Chart size. The multiplication chart 22 by 22 has 484 squares and the 23 by 23 has 529, and like the 24 each prints on one landscape page.
Which answers appear only once on the chart?
Seventeen, and every one is a square number: 1, 25, 49, 81, 121, then each square from 169 to 576. Squares such as 36, 64, 100 and 144 miss the list because other pairs reach them: 4 × 9, 4 × 16, 5 × 20 and 6 × 24.
How do I divide by 24 with this chart?
Look along the tinted row for the number you are dividing, then read the heading above it. 312 sits under 13, so 312 ÷ 24 = 13. A number that is not in the row does not divide by 24 evenly.
