After learning the table of 19, the table of 20 will be a relief for children as it is one of the easiest multiplication tables to learn. The 20 series is as easy to understand as the 5 and 10 series. If you're good at 2 tables, you'll find 20 tables pretty easily. It can be represented by arithmetic operations such as multiplication and repeated addition.
I have provided a chart here for students to study 20 tables.

20 + 20 = 40 |
20 + 20 + 20 = 60 |
20 + 20 + 20 + 20 = 80 |
20 + 20 + 20 + 20 + 20 = 100 |
20 + 20 + 20 + 20 + 20 + 20 = 120 |

Calculations that require multiples of 20 are multiplied by 2 and that number, with a zero added to the last digit, so each number is even.
Problem 1:
Solve 20 times 15 plus 20 times 12.
Solution:
20 multiplied by 15 is 300
20 multiplied by 12 is 240
20 times 15 plus 20 times 12, i.e, 300 plus 240 is 540
Problem 2:
Solve 20 times 6 plus 20 times 8.
Solution:
20 multiplied by 6 is 120
20 multiplied by 8 is 160
20 times 6 plus 20 times 8, i.e, 120 plus 160 is 280
Problem 3:
Solve 20 times 20 minus 20 times 8.
Solution:
20 multiplied by 20 is 400
20 multiplied by 8 is 160
20 times 8 minus 20 times 20, i.e, 400 minus 160 is 240
Problem 4:
Solve 12 times 20 minus 20 times 6.
Solution:
20 multiplied by 6 is 120
20 multiplied by 12 is 240
20 times 6 minus 20 times 12,i.e, 240 minus 120 is 120
Problem 5:
Multiply 20 times 6 by 12 times 20.
Solution:
20 multiplied by 6 is 120
20 multiplied by 12 is 240
20 times 6 multiplied by 20 times 12 , i.e, 120 multiplied by 2400 is 28800
