20 Times Table — Tricks, Multiples, Examples

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.

How to Learn the 20 Times Table (Patterns, Not Memorizing)

Bhanzu teaches the few patterns that generate a table rather than drilling its facts into recall. Once you see why every product of 20 behaves the way it does, you can rebuild any row instead of reaching for it from memory. That kind of number sense and mental agility is exactly what carries forward into algebra.

The whole table of 20 falls out of one fact: $20 = 2 \times 10$. Each pattern below is just that fact, looked at from a different angle.

Pattern 1: 20n is double n, then a zero. Because $20 = 2 \times 10$, multiplying by 20 means doubling and then shifting one place value. For $20 \times 7$: double 7 to get 14, append a 0, and you have 140. The zero is the $\times 10$; the doubling is the $\times 2$.

Pattern 2: The 20s are the 10s doubled. Twenty is two tens, so $20 \times n$ is exactly double $10 \times n$, which means you reuse a table you already know. For $20 \times 9$: $10 \times 9 = 90$, and doubling gives 180.

Pattern 3: Every product ends in 0. Since 20 carries a factor of 10, every multiple of 20 lands on a number ending in zero. That single units-digit fact is a quick check: if your answer does not end in 0, the place value slipped.

Pattern 4: Split the multiplier by place value. A large row decomposes the way the number is written. For $20 \times 17$, read 17 as $10 + 7$, so $20 \times 17 = (20 \times 10) + (20 \times 7) = 200 + 140 = 340$. This is the distributive idea you will meet again as $20(10 + 7)$ in algebra.

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.
