Good news first. If you know the table of 2, you already know the table of 20.
That’s it. That’s the secret. Kids see 20 × 7 and picture something huge and scary. But 20 is just 2 with a zero stuck on the end. So 20 × 7 is 14, plus a zero. 140. Done.
Below you’ll find the multiplication table of 20 up to 20 × 20, four tricks that feel almost unfair, a free worksheet with an answer key, and answers to what parents and teachers keep asking. Prefer paper? Print this page or save it as a PDF from your browser.
Show Me the 20 × Table (1 to 12)
Here’s the chart, including the 20 times table up to 20 × 12 that most school tests use:
Multiplication | Result |
20 × 1 | 20 |
20 × 2 | 40 |
20 × 3 | 60 |
20 × 4 | 80 |
20 × 5 | 100 |
20 × 6 | 120 |
20 × 7 | 140 |
20 × 8 | 160 |
20 × 9 | 180 |
20 × 10 | 200 |
20 × 11 | 220 |
20 × 12 | 240 |
Read it out loud once. Twenty ones are twenty, twenty twos are forty, twenty threes are sixty. Feels a bit silly. The rhythm sticks anyway.

Some Olympiad and mental maths papers keep going, so here’s the rest:
Multiplication | Result |
20 × 13 | 260 |
20 × 14 | 280 |
20 × 15 | 300 |
20 × 16 | 320 |

Quick list of the multiples of 20 up to 200: 20, 40, 60, 80, 100, 120, 140, 160, 180, 200.
What Does the Multiplication Table for 20 Actually Mean?
“Twenty of something.” Twenty groups, twenty jumps, twenty copies. So 20 × 3 is 20 + 20 + 20 = 60.
Try this picture. Hold a ₹20 note. Five of them make ₹100. Ten make ₹200. Once the number is money in your hand, the table stops being a chant and turns into pocket maths.
4 Easy Tricks to Memorize the Table of 20
Nobody needs all four. Try each once, keep the one that feels natural, forget the rest.
1. Double it, then add a zero
This is the big one. Since 20 = 2 × 10, you double the number and put a zero on the end.
- 20 × 4: double 4 is 8, add a zero, 80
- 20 × 7: double 7 is 14, add a zero, 140
- 20 × 13: double 13 is 26, add a zero, 260
Can you double? Then you can do the whole table.
2. Skip count by 20
Start at zero and keep adding 20: 20, 40, 60, 80, 100, 120, 140, 160, 180, 200. It’s skip counting by 2 with a zero on every number. Try it on the stairs, or while waiting for the bus.
3. Spot the pattern in the answers
Look at the ones place. It’s always 0. Now look at the tens place: 2, 4, 6, 8, 0, 2, 4, 6, 8, 0. It repeats every five answers, and it’s the same as the last digits of the table of 2. Worked out 20 × 6 and the answer doesn’t end in 0? Something’s off.
4. Think in hundreds
A handy anchor. 20 × 5 = 100, so every five steps you cross another hundred. 20 × 10 is 200, 20 × 15 is 300, 20 × 20 is 400. Stuck on 20 × 8? Start at 100 and add three more 20s: 120, 140, 160. 160.
Bonus: How to Tell if a Number Is in the Table of 20
A number is a multiple of 20 only if it ends in 0 and the digit before the 0 is even.
- 140: ends in 0, and the tens digit is 4 (even). Yes, it’s 20 × 7.
- 150: ends in 0, but the tens digit is 5 (odd). No. It’s a multiple of 10, not 20.
- 260: ends in 0, and the tens digit is 6 (even). Yes, it’s 20 × 13.
- 135: doesn’t end in 0. No.
Honestly, it’s a lot for younger kids. Older students tend to like it.
How to Learn the 20 Times Table Faster
Tricks help you understand it. Habits help you keep it.
Keep it short. Five minutes a day beats an hour of panic the night before a test. [Add your own line here, like: “When I practised with my nephew, ten minutes after dinner worked far better than a long weekend session.”] And shuffle the order. Don’t just chant 20, 40, 60 in a row. Ask “20 × 8?”, then “20 × 3?”, then “20 × 12?” Tests don’t come in order, so why should practice?
Use real stuff when you can: ₹20 notes, coins, a row of pencils. Say it, write it, then try a word problem, because each one reaches your memory through a different door. Games help too. Flashcards, a race against a sibling, or rolling a die and multiplying by 20. And please, no drama over wrong answers. A mistake just shows which line needs another look. [Add your own line here, like: “My niece kept mixing up 20 × 6 and 20 × 7 until she started doubling first.”]

C: 12) 60 and 100, 13) 180
D: 14) ₹120, 15) 160 pencils, 16) 240 pages, 17) ₹300
E: 18) 18, then 180, 19) 100 + 60 = 160
F: 20) Yes (20 × 8), 21) No (the tens digit is odd), 22) Yes (20 × 13), 23) No
G: 24) 340 (double 17 is 34, add a zero), 25) 200 + 80 = 280
Where You’ll Use the Table of 20 in Real Life
Money is the big one, since ₹20 notes are everywhere. It also shows up in packs of 20, in scoring (20 overs in a T20 match, say), and in percentages, because 20% of something is just one-fifth of it. And it’s a lovely stepping stone to bigger mental maths.
Common Mistakes to Watch For
The classic is dropping the zero. 20 × 6 is 120, not 12. Kids double correctly, then forget the zero. Quick check: every answer in this table ends in 0.
Then there’s swapping 20 × 5 and 20 × 6. They sit side by side, so 100 and 120 get flipped. Hold onto the fact that 20 × 5 is the magic hundred.
And the quiet mistake? Memorising without understanding. A child who knows 20 × 4 means “four groups of twenty” can recover from a blank. A child who only learned “add a zero” without knowing why gets stuck on 20 × 12.
Conclusion
The table of 20 looks bigger than it is. Double the number and add a zero when you’re stuck, lean on “20 × 5 = 100” for everything in between, and check yourself with the last-digit pattern. Practise a little each day instead of cramming. Give it a week, and 20 × 8 stops being a question. It’s just 160.
