The 9 times table
Also written as the multiplication table of 9. Here it is in full to 9 x 20, with the patterns worth pointing out, the fact children trip on, and free practice that does not need a sign-up.
9 x 1 to 9 x 12
| 9 × 1 | 9 |
|---|---|
| 9 × 2 | 18 |
| 9 × 3 | 27 |
| 9 × 4 | 36 |
| 9 × 5 | 45 |
| 9 × 6 | 54 |
| 9 × 7 | 63 |
| 9 × 8 | 72 |
| 9 × 9 | 81 |
| 9 × 10 | 90 |
| 9 × 11 | 99 |
| 9 × 12 | 108 |
9 x 13 to 9 x 20
| 9 × 13 | 117 |
|---|---|
| 9 × 14 | 126 |
| 9 × 15 | 135 |
| 9 × 16 | 144 |
| 9 × 17 | 153 |
| 9 × 18 | 162 |
| 9 × 19 | 171 |
| 9 × 20 | 180 |
Schools usually require up to twelve. The rest is here for children who want it, and it is where mental arithmetic starts to pay off.
Worth pointing out
Patterns in the 9 times table
- Up to 9 x 10, the digits of every answer add to nine. 18 gives 9, 27 gives 9, 81 gives 9.
- Up to 9 x 10, the tens digit is always one less than the number you multiplied by. 9 x 7 starts with 6, so the answer is 63.
The easiest way to learn it
Multiply by ten and subtract the number. For 9 x 7, ten sevens are 70, take away 7, and you have 63. This works for every multiplier, including past ten.
The fact children get wrong
Two answers get swapped here, 54 and 63, from 9 x 6 and 9 x 7. The rules above catch both: for 9 x 6 the tens digit must be 5, and 5 plus 4 makes 9.
On the abacus
Nine is one heaven bead and four earth beads, a full column. On a soroban, multiplying by nine is usually done as ten lots minus one lot, which is the same trick in beads.
Charts build familiarity. Recall comes from retrieval, a few minutes a day. Print the times tables sprint, or try the free virtual abacus where multiplication becomes bead positions rather than something to memorise.
Common questions
What is the 9 times table?
The 9 times table is 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99, 108, continuing to 9 x 20 which is 180. It is the same thing as the multiplication table of 9: each answer is 9 added to the one before it.
What is the easiest way to learn the 9 times table?
Multiply by ten and subtract the number. For 9 x 7, ten sevens are 70, take away 7, and you have 63. This works for every multiplier, including past ten.
Which fact in the 9 times table do children get wrong most often?
Two answers get swapped here, 54 and 63, from 9 x 6 and 9 x 7. The rules above catch both: for 9 x 6 the tens digit must be 5, and 5 plus 4 makes 9.
What is 9 x 12?
9 x 12 is 108. Twelve is the highest multiplier most primary schools require, though children who go further will need up to 9 x 20, which is 180.
Every times table
If the tables are a struggle
The problem is usually not the table
A child who is still counting to work out 9 x 3 has no attention left for 9 x 8. Fluency underneath is what makes the tables stick, and it is what abacus training builds.
