Patterns that help you remember it
- The last digits repeat in a cycle of 1: 0.
- Every answer is even, because 1100 is even.
- Every answer ends in 0 or 5.
- Split it into tens and ones: 1100 × k = 1100 × k + 0 × k.
- Each answer is 1100 more than the one before, so you can count on in steps of 1100.
Building it from tables you already know
Every answer in the 1100 times table is double the answer in the 550 times table: 550 × 6 = 3,300, so 1100 × 6 = 6,600. To multiply 1100 by 9, multiply by 10 and take one 1100 away: 11,000 − 1100 = 9,900. To multiply by 11, multiply by 10 and add one more 1100: 11,000 + 1100 = 12,100. Multiplying by 4 is doubling twice: 1100 → 2,200 → 4,400.
Every multiple of 1100 is at least 1100, so there are none below 100 and 0 below 1,000. A number is in the 1100 times table exactly when it divides by 1100 with no remainder.
Odd, even and the last digit
Because 1100 is even, every answer in its table is even, which is a quick way to catch a wrong answer. Multiplying by 10 always puts a zero on the end: 1100 × 10 = 11,000, and 1100 × 100 = 110,000. Multiplying by 5 is half of multiplying by 10: half of 11,000 is 5,500.
Using the 1100 times table to divide
Every fact also works backwards: because 1100 × 7 = 7,700, you know 7,700 ÷ 1100 = 7 and 7,700 ÷ 7 = 1100. 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 1100 pencils. How many pencils are in 6 boxes?
Answer
6 × 1100 = 6,600 pencils. - Tickets cost $1100 each. How much do 4 tickets cost?
Answer
4 × $1100 = $4,400. - 3,300 chairs are set out in rows of 1100. How many rows are there?
Answer
3,300 ÷ 1100 = 3 rows. - A plant grows 1100 millimetres a week. How much does it grow in 11 weeks?
Answer
11 × 1100 = 12,100 millimetres.
Questions
What is 1100 × 12?
13,200.
What is half of 1100 × 8?
1100 × 8 = 8,800, and half of that is 4,400, which is 1100 × 4. Halving one factor halves the answer.
What is 1100 times 0?
0. Any number multiplied by zero is zero, because zero groups of 1100 contain nothing.
What is 1100 × 7 and 1100 × 8?
1100 × 7 = 7,700 and 1100 × 8 = 8,800. These two are the facts most people find hardest, so they are worth practising on their own.
Is 16,500 in the 1100 times table?
Yes: 16,500 ÷ 1100 = 15 with no remainder. 16,501 is not, because dividing it by 1100 leaves a remainder of 1.
How do I learn the 1100 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.
