Patterns that help you remember it
- The last digits repeat in a cycle of 1: 0.
- Every answer is even, because 900 is even.
- The digits of every answer add up to a multiple of 9.
- Every answer ends in 0 or 5.
- Split it into tens and ones: 900 × k = 900 × k + 0 × k.
- Each answer is 900 more than the one before, so you can count on in steps of 900.
Building it from tables you already know
Every answer in the 900 times table is double the answer in the 450 times table: 450 × 6 = 2,700, so 900 × 6 = 5,400. To multiply 900 by 9, multiply by 10 and take one 900 away: 9,000 − 900 = 8,100. To multiply by 11, multiply by 10 and add one more 900: 9,000 + 900 = 9,900. Multiplying by 4 is doubling twice: 900 → 1,800 → 3,600.
Every multiple of 900 is at least 900, so there are none below 100 and 1 below 1,000. A number is in the 900 times table exactly when it divides by 900 with no remainder.
Odd, even and the last digit
Because 900 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: 900 × 10 = 9,000, and 900 × 100 = 90,000. Multiplying by 5 is half of multiplying by 10: half of 9,000 is 4,500.
Using the 900 times table to divide
Every fact also works backwards: because 900 × 7 = 6,300, you know 6,300 ÷ 900 = 7 and 6,300 ÷ 7 = 900. 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 900 pencils. How many pencils are in 3 boxes?
Answer
3 × 900 = 2,700 pencils. - Tickets cost $900 each. How much do 6 tickets cost?
Answer
6 × $900 = $5,400. - 3,600 chairs are set out in rows of 900. How many rows are there?
Answer
3,600 ÷ 900 = 4 rows. - A plant grows 900 millimetres a week. How much does it grow in 11 weeks?
Answer
11 × 900 = 9,900 millimetres.
Questions
What is 900 × 12?
10,800.
What is half of 900 × 8?
900 × 8 = 7,200, and half of that is 3,600, which is 900 × 4. Halving one factor halves the answer.
What is 900 times 0?
0. Any number multiplied by zero is zero, because zero groups of 900 contain nothing.
What is 900 × 7 and 900 × 8?
900 × 7 = 6,300 and 900 × 8 = 7,200. These two are the facts most people find hardest, so they are worth practising on their own.
Is 13,500 in the 900 times table?
Yes: 13,500 ÷ 900 = 15 with no remainder. 13,501 is not, because dividing it by 900 leaves a remainder of 1.
How do I learn the 900 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.
