    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.

    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
