Patterns that help you remember it
- The last digits repeat in a cycle of 10: 9, 8, 7, 6, 5, 4, 3, 2, 1, 0.
- The digits of every answer add up to a multiple of 9.
- Split it into tens and ones: 1089 × k = 1080 × k + 9 × k.
- Each answer is 1089 more than the one before, so you can count on in steps of 1089.
Building it from tables you already know
To multiply 1089 by 9, multiply by 10 and take one 1089 away: 10,890 − 1089 = 9,801. To multiply by 11, multiply by 10 and add one more 1089: 10,890 + 1089 = 11,979. Multiplying by 4 is doubling twice: 1089 → 2,178 → 4,356.
Every multiple of 1089 is at least 1089, so there are none below 100 and 0 below 1,000. A number is in the 1089 times table exactly when it divides by 1089 with no remainder.
Odd, even and the last digit
Because 1089 is odd, the answers alternate between odd and even: 1089 × 1 = 1089 is odd, 1089 × 2 = 2,178 is even, and so on. Multiplying by 10 always puts a zero on the end: 1089 × 10 = 10,890, and 1089 × 100 = 108,900. Multiplying by 5 is half of multiplying by 10: half of 10,890 is 5,445.
Using the 1089 times table to divide
Every fact also works backwards: because 1089 × 7 = 7,623, you know 7,623 ÷ 1089 = 7 and 7,623 ÷ 7 = 1089. Practising the table and its division facts together halves the work.

Word problems
Times tables are most useful when you can spot them in a question. Try these, then open each one to check:
- A box holds 1089 pencils. How many pencils are in 9 boxes?
Answer
9 × 1089 = 9,801 pencils. - Tickets cost $1089 each. How much do 7 tickets cost?
Answer
7 × $1089 = $7,623. - 9,801 chairs are set out in rows of 1089. How many rows are there?
Answer
9,801 ÷ 1089 = 9 rows. - A plant grows 1089 millimetres a week. How much does it grow in 10 weeks?
Answer
10 × 1089 = 10,890 millimetres.
Questions
What is 1089 × 12?
13,068.
What is half of 1089 × 8?
1089 × 8 = 8,712, and half of that is 4,356, which is 1089 × 4. Halving one factor halves the answer.
What is 1089 times 0?
0. Any number multiplied by zero is zero, because zero groups of 1089 contain nothing.
What is 1089 × 7 and 1089 × 8?
1089 × 7 = 7,623 and 1089 × 8 = 8,712. These two are the facts most people find hardest, so they are worth practising on their own.
Is 16,335 in the 1089 times table?
Yes: 16,335 ÷ 1089 = 15 with no remainder. 16,336 is not, because dividing it by 1089 leaves a remainder of 1.
How do I learn the 1089 times table quickly?
Learn it in order first, then use the patterns above and practise mixed questions; a few minutes a day works better than one long session.
