20 Times Table

Learn the 20 times table in an easy and fun way

We’ve finally reached the number 20 on the multiplication tables. Learning how to multiply is an essential skill, that’ll help you in all walks of life. Now that we’ve learnt the multiplication tables for the numbers 1 to 19, it’s time to learn the 20 times table.

After the 5 and 10 times tables, the 20 times multiplication table is the easiest to learn. In the 10 times table, you just have to add a ‘0’ at the end of the digit to get the multiples of 10. Similarly, you’ll have to add a ‘0’ at the end of the digit in the 20 times multiplication table too. But here, you’ll have to double the number to get the first digit.

First, let’s have a look at the 20 times table

20X1=20
20X2=40
20X3=60
20X4=80
20X5=100
20X6=120
20X7=140
20X8=160
20X9=180
20X10=200

Learning the 20 times multiplication table is quite easy. However, if you still need help in learning the tables, here are some simple tips and tricks. These tips and tricks will help you master the 20 times multiplication table easily and quickly.

It’s just the 2 times table with a 0 at the end

Here’s an easy way to look at the 20 times table. The 20 times multiplication table is just the 2 times table with a zero at the end. So, if you’re confident with the 2 times tables, just write that down first. Now just add a zero at the end of each multiple of 2 and you’ll get the multiples of 20. Here is an example to help you understand.

Let’s find out what 20 X 5 is.

First, write down what 2 X 5 is. 2 X 5 = 10.

Now, to get the multiple of 20, add a zero at the end of 10. So, you get 100.

So, 20 X 5 = 100.

Let’s try another example.

Let’s find out what 20 X 8 is.

First, find out what 2 X 8 is. 2 X 8 = 16.

Now, to get the answer for 20 X 8, add a zero at the end of 16. So, you get 160.

So, 20 X 8 = 160.

Using this method, you can get all the multiples of 20 from 20 X 1 to 20 X 10.

Double the 10 times table

Are you still confused? Here is another neat trick that’ll help you learn the 20 times multiplication tables in no time at all. And if you’re confident with the 10 times tables, you’ll find this method very easy. First, write down the 10 times table. Remember, in the 10 times table you multiply the numbers by 1, and add a zero at the end of the digit. 

10 is half of 20. So, to get the multiples of 20, just double the multiples of 10. Here is an example to help you understand.

Let’s find out what 20 X 2 is.

First, find out what 10 X 2 is. 10 X 2 = 20.

Now, double the answer. 20 + 20 = 40.

So, 20 X 2 = 40.

Let’s try another example using the same method.

Let’s find out what 20 X 6 is.

First, find out what 10 X 6 is. 10 X 6 = 60.

Now, double the answer. 60 + 60 = 120.

So, 20 X 6 = 120.

Add 20 to the previous multiple

If you still find it difficult to learn how to multiply by 20, try the addition trick. A simple way to find out the multiples of 20 is to add 20 to the previous answer. Here is an example to help you understand.

Let’s find out what 20 X 2 is.

We know 20 X 1 = 20.

To find out 20 X 2, add 20 to the answer for 20 X 1.

So, 20 + 20 = 40.

Therefore, 20 X 2 = 40.

Let’s try another example.

Let’s find out what 20 X 3 is.

We know 20 X 2 = 40.

To find out 20 X 3, add 20 to the answer for 20 X 2.

So, 40 + 20 = 60.

Therefore, 20 X 3 = 60.

Similarly, add 20 to each of the previous answers to get all the multiples of 10 till 20 X 10.

The underlying pattern

The 20 times table has a very cool pattern. Look at the table below.

20X1=2 0
20X2=4 0
20X3=6 0
20X4=8 0
20X5=10 0
20X6=12 0
20X7=14 0
20X8=16 0
20X9=18 0
20X10=20 0

Look at the digits in the ones column (in black), they’re all zeros. Now look at the digits in the tens column (in purple), they’re all even numbers. And the numbers are in sequential order, 2, 4, 6, 8.10, 12, 14, 16, 18 and 20. Remember this pattern and you’ll be able to learn the 20 times table easily.

Train your brain

The best way to learn the 20 times multiplication table is to practice it constantly. Train your brain to memorize the times table.
