What is the Mathematics 20s Table?

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 + 20 = 40

20 + 20 + 20 = 60

20 + 20 + 20 + 20 = 80

20 + 20 + 20 + 20 + 20 = 100

20 + 20 + 20 + 20 + 20 + 20 = 120

20 + 20 + 20 + 20 + 20 + 20 + 20 = 140

20 + 20 + 20 + 20 + 20 + 20 + 20 + 20 = 160

20 + 20 + 20 + 20 + 20 + 20 + 20 + 20 + 20 = 180

20 + 20 + 20 + 20 + 20 + 20 + 20 + 20 + 20 + 20 = 200
