The usefulness of the 1-20 table
These are very useful for doing complicated calculations easily and quickly.
It helps to overcome the errors which we can encounter while calculating it in our head.
It is useful for identifying the patterns of multiplication of different numbers all ranging between 1 to 20.
Solved examples
Example 1: By taking the help from the table of 1 to 20 calculate 8 times 16.
Solution:
Firstly we will look over the table of 1 to 20 and write 8 times 16 in a mathematical form which is:
8 times 16 = 8 × 16 = 128
Thus by tables from 1 to 20, we obtain the result of 8 times 16 as 128.
Example 2: Find the product of 14 and 3 following the 1 to 20 table.
Solution:
Firstly, we will be writing the given question in a mathematical form.
And by using the table of 14 we can say that,
Product of 14 and 3 = 14 × 3 = 42
Thus, the multiplication of 14 and 3 using tables of 1 to 20 will give the result of 42.
Example 3: Examine all of the different tables from 1 to 20 and try to assess 19 times 9.
Solution:
Initially, we will perceive all of the tables from 1 to 20 as well as calculate 19 times 9 as
19 times 9 = 19× 9 = 171
Observing all of the tables from 1 to 20, we get 19 times 9 equals 171.
