The 9 times table has more tricks than any other table. The finger trick, the rising-and-falling digit pattern, and its relationship to the 10 times table make it surprisingly easy.

| 9 × 10 | 90 |
| 9 × 11 | 99 |
| 9 × 12 | 108 |
The finger trick
Hold up all ten fingers. For 9 × 4, bend the 4th finger from the left. The 3 fingers to the left of it are the tens, the 6 to the right are the ones. Answer: 36. Works for 9 × 1 through 9 × 10.
10 times minus one
9 × a number = 10 × that number − the number. 9 × 7 = 70 − 7 = 63. Almost always faster than remembering the fact itself.
Digits add up to 9
9 × 2 = 18 (1 + 8 = 9). 9 × 5 = 45 (4 + 5 = 9). 9 × 7 = 63 (6 + 3 = 9). Up to 9 × 10, every answer's digits sum to 9 — a perfect way to check.
Children typically learn the multiplication tables in Grades 2 and 3 (ages 7–9). The tables of 2, 5 and 10 are taught first, then 3, 4 and 6, and finally the harder tables of 7, 8 and 9. Most children know all tables up to 10 by the end of Grade 3.
What is 9 × 7?+
9 × 7 = 63. Check: 6 + 3 = 9, so it works out. Or compute: 10 × 7 − 7 = 70 − 7 = 63.
What is the finger trick for the 9 times table?+
Hold up all ten fingers. For 9 × N, bend the Nth finger from the left. The fingers to its left are the tens, the fingers to its right are the ones. For 9 × 3: bend finger 3 → 2 on the left, 7 on the right → 27.
Why do the digits of the 9 times table always add up to 9?+
Because 9 is one less than 10. Each time you add another 9, the tens digit goes up by 1 and the ones digit goes down by 1, so the digit sum stays at 9.
What grade do children learn the 9 times table?+
The 9 times table is taught in Grade 3, often as the last of the harder tables.
