9 times table, the finger trick and the digits that add to 9.

The 9 times table is full of patterns: 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99, 108 up to 9 × 12. The digits of each answer add up to 9, the tens digit climbs while the ones digit falls, and your ten fingers show the first ten facts. The tool above shows the table with its digit sum card, hides answers, runs a scored quiz and prints a chart or sheet.

The 9 times table, 1 to 12

The finger trick

Hold both hands out in front of you and number your fingers 1 to 10 from left to right. To find 9 × 4, fold down your fourth finger. There are 3 fingers to the left of it and 6 to the right, so the answer is 36. For 9 × 7, fold down the seventh finger: 6 fingers on the left and 3 on the right give 63. For 9 × 10, fold down the tenth finger: 9 on the left, none on the right, so 90. It works from 9 × 1 to 9 × 10.

Digits that add to 9

Add the digits of each answer in the table: 1 + 8 = 9, 2 + 7 = 9, 3 + 6 = 9, 4 + 5 = 9, 5 + 4 = 9, 6 + 3 = 9, 7 + 2 = 9, 8 + 1 = 9, 9 + 0 = 9. After 90, the pattern still works if you keep adding: 99 gives 18, then 1 + 8 = 9, and 108 gives 1 + 0 + 8 = 9. If a number is in the 9 times table, its digits add up to 9, 18 or 27 and on. 4,572 gives 4 + 5 + 7 + 2 = 18, so 4,572 = 9 × 508.

Tens go up, ones go down

For 9 × 1 to 9 × 10 the tens digit climbs 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 and the ones digit falls 9, 8, 7, 6, 5, 4, 3, 2, 1, 0. The answers also come in reverse pairs: 18 and 81, 27 and 72, 36 and 63, 45 and 54.

Ten minus one

Nine is one less than ten. 9 × 8 is 10 × 8 minus 8, which is 80 minus 8 = 72. This extends past 10: 9 × 12 is 120 minus 12, which is 108.

Worked examples

• Finger trick. 9 × 6: fold down finger 6, which leaves 5 on the left and 4 on the right. The answer is 54.
• Digit check. Is 81 right for 9 × 9? 8 + 1 = 9, so yes.
• Division. 63 ÷ 9 = 7, because 9 × 7 = 63.
• Missing number. 9 × ? = 108. The answer is 12.
• Past 12. 9 × 13 is 117 (1 + 1 + 7 = 9). 9 × 20 = 180.

Beyond 12: 9 × 13 to 9 × 20

Set Go up to to 20 and the tool shows these as well. For any of them, split the number: 9 × 13 is 9 × 10 plus 9 × 3, which is 90 + 27 = 117.

Common mistakes

• Giving 9 × 7 as 56 or 64. It is 63.
• Saying 9 × 9 = 18, which is 9 + 9 and 9 × 2. The answer is 81.
• Using the finger trick past 10. It stops at 9 × 10, so use ten minus one for 11 and 12.

A way to learn it

Learn the finger trick first, then the digit sum, then check your answers with it. Hide the answers and take the quiz. Facts 9 × 11 = 99 and 9 × 12 = 108 come last: 99 repeats the digit, and 108 is 120 minus 12.
