shortcut way for learning table of 20

Answer 1

if u know the table of 2 then just add 0s in table of 2 .

for example: 2×2=4
20×2=40

Answer 2

The answer is given below :

We know that,

2 × 1 = 2
2 × 2 = 4
2 × 3 = 6
2 × 4 = 8
2 × 5 = 10
2 × 6 = 12
2 × 7 = 14
2 × 8 = 16
2 × 9 = 18
2 × 10 = 20.

Now, 20 has a zero at ones place.

So, the previous multiplications give (we put a zero after 2 in the first column and another zero after the numbers in the 3rd column).

So, the table is like this :

20 × 1 = 20
20 × 2 = 40
20 × 3 = 60
20 × 4 = 80
20 × 5 = 100
20 × 6 = 120
20 × 7 = 140
20 × 8 = 160
20 × 9 = 180
20 × 10 = 200
