Multiplication Table of 20
The 20 times table is the list of products you get when you multiply 20 by each whole number in turn. It is one of the friendliest of the larger tables, because 20 is just $2 \times 10$, so every multiple ends in a zero and climbs in even steps.

Table of 20 in Words
Reading the table aloud builds the rhythm before the numbers stick. Here is the table of 20 spoken out, row by row.
One times 20 is 20
Two times 20 is 40
Three times 20 is 60
Four times 20 is 80
Five times 20 is 100
Six times 20 is 120
Seven times 20 is 140
Eight times 20 is 160
Nine times 20 is 180
Ten times 20 is 200
What Is the 20 Times Table?
The 20 times table is repeated addition of 20. Each row adds one more group of twenty, so the table is really the answer to "how much is twenty, added to itself, again and again?"
You can build every product from scratch by stacking twenties:
$20$
$20 + 20 = 40$
$20 + 20 + 20 = 60$
$20 + 20 + 20 + 20 = 80$
Keep going and you reach $20 \times 10 = 200$. Multiplication is the shortcut for this addition ladder, which is why $20 \times 5$ and "five twenties added up" give the same 100.
Multiples of 20
The multiples of 20 are the numbers you land on when skip-counting by twenty. The first twenty multiples are:
20, 40, 60, 80, 100, 120, 140, 160, 180, 200, 220, 240, 260, 280, 300, 320, 340, 360, 380, 400.
Every entry in the 20 times table is a multiple of 20, and every multiple of 20 is also a multiple of 10 and of 2. That is why each one ends in a zero.
Tips and Tricks to Memorize the 20 Times Table
The table of 20 leans almost entirely on tables you already know. Here are the routes that do the most work.
Trick 1: Double and add a zero. Double the multiplier (that is the 2 times table), then write a 0 after it. For $20 \times 7$: double 7 to get 14, add a zero, and you have 140.
Trick 2: Use the 2 times table with a place-value shift. The multiples of 2 are 2, 4, 6, 8, 10, 12 … Add a zero to each and you get 20, 40, 60, 80, 100, 120, which is the table of 20 exactly.
Trick 3: Double the 10 times table. Twenty is two tens, so $20 \times n$ is double $10 \times n$. For $20 \times 9$: $10 \times 9 = 90$, doubled is 180.
Trick 4: Decompose a big multiplier. For a row that feels large, split the multiplier. For $20 \times 17$, break 17 into $10 + 7$: $20 \times 10 = 200$ and $20 \times 7 = 140$, so $200 + 140 = 340$.
How to Read and Use the 20 Times Table
Read each row left to right: $20 \times 6 = 120$ is "twenty multiplied six times gives one hundred twenty." The first number is the group size (20), the second is how many groups, and the product is the total.
To learn it, skip-count out loud (20, 40, 60, 80) until the sequence runs without effort, then test yourself in a random order so you are recalling facts, not reciting a chant. Short daily practice beats one long session, so come back to the chart whenever a row feels shaky.
Where the 20 Times Table Appears
The 20 times table is the arithmetic behind anything counted in twenties: a roll of twenty-rupee or twenty-dollar notes, a carton holding 20 packs, or a cricket innings of twenty overs. It also sits one step from percentages, since finding 20% of a value uses the same multiples, which is why a shopkeeper working out a one-fifth discount reaches for the table of 20 without thinking.
Solved Examples
Example 1
What is $20 \times 6$?
Double the 6 to get 12, then add a zero.
$20 \times 6 = 120$
Final answer: $20 \times 6 = 120$.
Example 2 (Wrong path first)
A shelf holds 20 books. How many books are on 8 such shelves?
Wrong attempt. The rusher reads $20 \times 8$ as just $2 \times 8$ and stops at 16.
Why it breaks. Eight shelves of twenty books each must hold more than a single shelf, so 16 cannot be right; it is less than one shelf's 20.
Correct. Double the 8 to get 16, then add the zero that belongs to the 20.
$20 \times 8 = 160$
Final answer: 160 books.
Example 3
Find $20 \times 15$.
Split 15 into $10 + 5$:
$20 \times 10 = 200$
$20 \times 5 = 100$
$200 + 100 = 300$
Final answer: $20 \times 15 = 300$.
Example 4
$20 \times {?} = 240$.
Divide to find the missing factor: $240 \div 20 = 12$.
Final answer: $20 \times 12 = 240$.
Example 5
A bus carries 20 passengers per trip and makes 18 trips in a day. How many passengers in total?
$20 \times 18 = (20 \times 10) + (20 \times 8) = 200 + 160 = 360$.
Final answer: 360 passengers.
Common Mistakes
Mistake 1: Adding one zero too few, or one too many
Where it slips in: Rushing the double-and-add-zero trick and losing track of the single zero that belongs to the 20.
Don't do this: Writing $20 \times 6$ as 12 (doubled but no zero) or as 1,200 (an extra zero crept in).
The correct way: Double once, then add exactly one zero. Six doubles to 12, and one zero gives 120.
Mistake 2: Confusing the table of 20 with the table of 2
Where it slips in: The first instinct under time pressure is to read $20 \times 8$ as $2 \times 8$ and stop at 16, dropping the place value of the 20.
Don't do this: Answering $20 \times 8 = 16$.
The correct way: $20 \times 8 = 160$. The 16 is right; the missing zero is what turns it into the table of 20.
