Patterns that help you remember it
- The last digits repeat in a cycle of 5: 2, 4, 6, 8, 0.
- Every answer is even, because 1812 is even.
- Split it into tens and ones: 1812 × k = 1810 × k + 2 × k.
- Each answer is 1812 more than the one before, so you can count on in steps of 1812.
Building it from tables you already know
Every answer in the 1812 times table is double the answer in the 906 times table: 906 × 6 = 5,436, so 1812 × 6 = 10,872. To multiply 1812 by 9, multiply by 10 and take one 1812 away: 18,120 − 1812 = 16,308. To multiply by 11, multiply by 10 and add one more 1812: 18,120 + 1812 = 19,932. Multiplying by 4 is doubling twice: 1812 → 3,624 → 7,248.
Every multiple of 1812 is at least 1812, so there are none below 100 and 0 below 1,000. A number is in the 1812 times table exactly when it divides by 1812 with no remainder.
Odd, even and the last digit
Because 1812 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: 1812 × 10 = 18,120, and 1812 × 100 = 181,200. Multiplying by 5 is half of multiplying by 10: half of 18,120 is 9,060.
Using the 1812 times table to divide
Every fact also works backwards: because 1812 × 7 = 12,684, you know 12,684 ÷ 1812 = 7 and 12,684 ÷ 7 = 1812. Practising the table and its division facts together halves the work.

Questions
What is 1812 × 12?
21,744.
What is half of 1812 × 8?
1812 × 8 = 14,496, and half of that is 7,248, which is 1812 × 4. Halving one factor halves the answer.
What is 1812 times 0?
0. Any number multiplied by zero is zero, because zero groups of 1812 contain nothing.
What is 1812 × 7 and 1812 × 8?
1812 × 7 = 12,684 and 1812 × 8 = 14,496. These two are the facts most people find hardest, so they are worth practising on their own.
Is 27,180 in the 1812 times table?
Yes: 27,180 ÷ 1812 = 15 with no remainder. 27,181 is not, because dividing it by 1812 leaves a remainder of 1.
How do I learn the 1812 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.
