Patterns that help you remember it
- The last digits repeat in a cycle of 5: 8, 6, 4, 2, 0.
- Every answer is even, because 1388 is even.
- Split it into tens and ones: 1388 × k = 1380 × k + 8 × k.
- Each answer is 1388 more than the one before, so you can count on in steps of 1388.
Building it from tables you already know
Every answer in the 1388 times table is double the answer in the 694 times table: 694 × 6 = 4,164, so 1388 × 6 = 8,328. To multiply 1388 by 9, multiply by 10 and take one 1388 away: 13,880 − 1388 = 12,492. To multiply by 11, multiply by 10 and add one more 1388: 13,880 + 1388 = 15,268. Multiplying by 4 is doubling twice: 1388 → 2,776 → 5,552.
Every multiple of 1388 is at least 1388, so there are none below 100 and 0 below 1,000. A number is in the 1388 times table exactly when it divides by 1388 with no remainder.
Odd, even and the last digit
Because 1388 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: 1388 × 10 = 13,880, and 1388 × 100 = 138,800. Multiplying by 5 is half of multiplying by 10: half of 13,880 is 6,940.
Using the 1388 times table to divide
Every fact also works backwards: because 1388 × 7 = 9,716, you know 9,716 ÷ 1388 = 7 and 9,716 ÷ 7 = 1388. Practising the table and its division facts together halves the work.

Answer
4 × 1388 = 5,552 pencils. - Tickets cost $1388 each. How much do 5 tickets cost?
Answer
5 × $1388 = $6,940. - 5,552 chairs are set out in rows of 1388. How many rows are there?
Answer
5,552 ÷ 1388 = 4 rows. - A plant grows 1388 millimetres a week. How much does it grow in 12 weeks?
Answer

Questions
What is 1388 × 12?
16,656.
What is half of 1388 × 8?
1388 × 8 = 11,104, and half of that is 5,552, which is 1388 × 4. Halving one factor halves the answer.
What is 1388 times 0?
0. Any number multiplied by zero is zero, because zero groups of 1388 contain nothing.
What is 1388 × 7 and 1388 × 8?
1388 × 7 = 9,716 and 1388 × 8 = 11,104. These two are the facts most people find hardest, so they are worth practising on their own.
Is 20,820 in the 1388 times table?
Yes: 20,820 ÷ 1388 = 15 with no remainder. 20,821 is not, because dividing it by 1388 leaves a remainder of 1.
How do I learn the 1388 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.
