3 times table: trick and speed drill
Double it, then add one more lot. Then put it to work with a free 60-second drill.
The trick for the 3 times table
Double it, then add one more lot. 3 × n is 2 × n plus n. To check a 3 times table answer, add its digits: if the total divides by 3, so does the number.
- 3 × 27 = 54 + 27 = 81
- 3 × 46 = 92 + 46 = 138
- Check 138: 1 + 3 + 8 = 12, which divides by 3
How the drill works
You get 60 seconds of 3 times table questions in both directions: multiplication like 3 × 7 and division like 21 ÷ 3. Type the answer and it is accepted the moment it is right. Your scores, best and slowest facts are saved on your device, so you can see the table getting quicker.

Questions people ask
What is the fastest way to learn the 3 times table?
Learn one shortcut (double it, then add one more lot) and then drill it under a timer for a minute a day. Speed comes from repetition, not from reading the table.
How do I check a 3 times table answer quickly?
Estimate first: round the other number to the nearest 10 and multiply. If your answer is far from the estimate, recheck it.
Is the 3 times table tested in trading interviews?
Trading firm arithmetic tests use mixed questions rather than one table, but fast table facts are what make the bigger sums quick.
