20 x 13 = 260
20 x 14 = 280
20 x 15 = 300
20 x 16 = 320
20 x 17 = 340
20 x 18 = 360
20 x 19 = 380
20 x 20 = 400

There are many tips to memorize the 20 times table, but we have mentioned the easiest one here. Recall the multiplication table of 2 and add 0 at its multiples’ unit’s place. By doing so, you will obtain the multiples of 20 times table. Go through the table below to see how this tip works:
| 2 Times Table | Add 0 to Unit’s Place | 20 Times Table |
| 2 x 1 = 2 | 20 | 20 x 1 = 20 |
| 2 x 2 = 4 | 40 | 20 x 2 = 40 |
| 2 x 3 = 6 | 60 | 20 x 3 = 60 |
| 2 x 4 = 8 | 80 | 20 x 4 = 80 |
| 2 x 5 = 10 | 100 | 20 x 5 = 100 |
| 2 x 6 = 12 | 120 | 20 x 6 = 120 |
| 2 x 7 = 14 | 140 | 20 x 7 = 140 |
| 2 x 8 = 16 | 160 | 20 x 8 = 160 |
| 2 x 9 = 18 | 180 | 20 x 9 = 180 |
| 2 x 10 = 20 | 200 | 20 x 10 = 200 |
Another tip for memorizing the 20 times table is to use the repeated addition method. Add 20 into the product of multipliers to generate the next product.
For example,
20 x 1 = 20
20 x 2 = 20 + 20 = 40
20 x 3 = 20 + 20 + 20 = 60
20 x 4 = 20 + 20 + 20 + 20 = 80
20 x 5 = 20 + 20 + 20 + 20 + 20 = 100
20 x 6 = 20 + 20 + 20 + 20 + 20 + 20 = 120 and so on.
Solution:
Given that,
20 times 9 minus 20 times 5
Mathematically it is written as
= 20 x 9 – 20 x 5
= 180 – 100
= 80
Thus, the value of 20 times 9 minus 20 times 5 is 80.
___ x 20 = 120
20 x ___ = 80
___ x ___ = 240
___ x 17 = ___
___ x 2 = 40
20 x ___ = 380
___ x 9 = ___
___ x ___ = 140
___ x 20 = 300
___ x ___ = 180
Solution:
20 times 7 and 20 times 17
= 20 x 7 and 20 x 17
= 140 and 340
Hence, the value of 20 times 7 and 20 times 17 is 140 and 340, respectively.
Solution:
Given that,
Total chocolates = 15
Cost of one chocolate = 20$
Using table of 20
Cost of 15 chocolates = 15 x 20 = 300
Hence, the cost of 15 chocolates is 300$.
Solution:
Given that,
20 times 6
In mathematical form,
= 20 x 6
= 120
The number before 120 = 120 – 1 = 119
The number after 120 = 120 + 1 = 121
Hence, a number before and after 20 times 6 is 119 and 121, respectively.
