20 Times Table — Tricks, Multiples, Examples

TL;DR

The 20 times table lists the multiples of 20: 20 × 10 = 200 and 20 × 20 = 400, with every product ending in zero. This article covers the full chart to ×20, the table in words, the multiples of 20, the double-and-add-zero trick, worked examples, and the mistakes to avoid.

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 2×10, 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 = 40 20 + 20 + 20 = 60 20 + 20 + 20 + 20 = 80 Keep going and you reach 20×10 = 200. Multiplication is the shortcut for this addition ladder, which is why 20×5 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.

The whole table of 20 falls out of one fact: 20 = 2 × 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 × 10, multiplying by 20 means doubling and then shifting one place value. For 20×7: double 7 to get 14, append a 0, and you have 140.

Pattern 2: The 20s are the 10s doubled.
Twenty is two tens, so 20×n is exactly double 10×n.

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.

Pattern 4: Split the multiplier by place value.
A large row decomposes the way the number is written. For 20×17, read 17 as 10+7, so 20×17=(20×10)+(20×7)=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: 20×6=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. 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.

Solved Examples

Example 1

What is 20×6?
Double the 6 to get 12, then add a zero.
Final answer: 20×6 = 120.

Example 2 (Wrong path first)

A shelf holds 20 books. How many books are on 8 such shelves?
Wrong attempt. The rusher reads 20×8 as just 2×8 and stops at 16.

Correct. Double the 8 to get 16, then add the zero that belongs to the 20.
Final answer: 160 books.

Example 3

Find 20×15.
Split 15 into 10+5: 20×10=200 20×5=100 200+100=300
Final answer: 20×15 = 300.

Example 4

20×?=240.
Divide to find the missing factor: 240÷20=12.
Final answer: 20×12 = 240.

Example 5

A bus carries 20 passengers per trip and makes 18 trips in a day. How many passengers in total?
20×18=(20×10)+(20×8)=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.

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 is to read 20×8 as 2×8 and stop at 16.

The correct way: 20×8=160. The 16 is right; the missing zero is what turns it into the table of 20.

Frequently Asked Questions

What is the 20 times table up to 20?
It runs from 20×1=20 to 20×20=400.

What is 20 times 12?
20×12=240. Double 12 to get 24, then add a zero.

Why does every multiple of 20 end in zero?
Because 20 is a multiple of 10, and anything multiplied by a multiple of 10 lands on a number ending in zero.

Is 20 an even number, so are all its multiples even?
Yes. Twenty is even, and any whole number times an even number stays even.

What is 20 times 20?
400. Double 20 to get 40, then add a zero.
