7 times 9 is 63 — with the shortcut, the division facts and a drill to make it stick
7 × 9 = 63. Your fingers hold the answer, and a digit check catches the slips that swap it with 8 × 9.
7 × 9 = 63. Said out loud in the way most classrooms say it: Seven nines are sixty-three.
9 + 9 + 9 + 9 + 9 + 9 + 9 = 63 — that is seven nines added together.
Hold up ten fingers and fold down the seventh. Six fingers stand to its left and three to its right: 63. It works for every nines fact up to 9 × 10.
Alternatively, nine sevens is ten sevens minus one seven: 70 − 7 = 63. The digits of 63 add to 9, as every nine-times answer up to 90 does.
This fact gets swapped with 8 × 9 = 72 and 7 × 8 = 56 more than any other. Checking the tens digit catches it: in 7 × 9 the tens digit is one less than 7, so it has to be 6.
Method 1, split 9 into 5 + 4: 7 × 5 = 35 (half of 7 × 10 = 70) and 7 × 4 = 28. Add them: 35 + 28 = 63.
Method 2, the near-square trick (both are 1 from 8): 7 and 9 sit 1 either side of 8, so the answer is 8 × 8 minus 1 × 1: 64 − 1 = 63.
Use the nines rule. The tens digit is one less than the number you are multiplying — one less than 7 is 6 — and the two digits always add up to nine, so the answer is 63. Check it: 6 + 3 = 9.
Both factors are odd, so the answer has to be odd as well. 63 is odd, which rules out a whole class of slips.
7 × 9 = 63, 9 × 7 = 63, 63 ÷ 7 = 9 and 63 ÷ 9 = 7 are one fact read in different directions. The facts either side — 7 × 8 = 56, 7 × 10 = 70, 6 × 9 = 54, 8 × 9 = 72 — are the answers people most often give by mistake when rushing, and each is just one seven or one nine away from 63.
63 appears twice in the grid: as 7 × 9 in the seven times table and as 9 × 7 in the nine times table. The highlighted row shows both.
| × | 7 times table | 9 times table |
|---|---|---|
| 1 | 7 × 1 = 7 | 9 × 1 = 9 |
| 2 | 7 × 2 = 14 | 9 × 2 = 18 |
| 3 | 7 × 3 = 21 | 9 × 3 = 27 |
| 4 | 7 × 4 = 28 | 9 × 4 = 36 |
| 5 | 7 × 5 = 35 | 9 × 5 = 45 |
| 6 | 7 × 6 = 42 | 9 × 6 = 54 |
| 7 | 7 × 7 = 49 | 9 × 7 = 63 |
| 8 | 7 × 8 = 56 | 9 × 8 = 72 |
| 9 | 7 × 9 = 63 | 9 × 9 = 81 |
| 10 | 7 × 10 = 70 | 9 × 10 = 90 |
| 11 | 7 × 11 = 77 | 9 × 11 = 99 |
| 12 | 7 × 12 = 84 | 9 × 12 = 108 |
These are the facts one step away from 7 × 9 in the grid, and the answers people give by mistake when rushing. The last column shows how far each lands from 63; tap a fact to open it or its times table.

7 times 9 is 63. In words, seven nines are sixty-three.
63 ÷ 7 = 9, because 7 × 9 = 63. The matching fact is 63 ÷ 9 = 7.
Method 1, split 9 into 5 + 4: 7 × 5 = 35 (half of 7 × 10 = 70) and 7 × 4 = 28. Add them: 35 + 28 = 63. Method 2, the near-square trick (both are 1 from 8): 7 and 9 sit 1 either side of 8, so the answer is 8 × 8 minus 1 × 1: 64 − 1 = 63.
Yes. Multiplication can be done in either order, so 7 × 9 and 9 × 7 both equal 63.
1, 3, 7, 9, 21 and 63. Up to 10 × 10, 7 × 9 is the only times-table fact that gives 63.
The digits of every multiple of 9 up to 90 add up to 9 (6 + 3 = 9), and the tens digit is one less than the number multiplied by 9 (7 − 1 = 6).
Every times table from 1 to 20 is written out on the times tables page, with a drill for any row, and the full grid is on the multiplication chart.
