Tips and Tricks for learning Table of 21

We all learnt tables when we were kids and it was really the difficult of all learning tasks. Since we didn’t understand if there could be any tips and tricks in learning tables, we were left with no options other than just CRAME it.

Today in this vlog, we are going to show you how to learn table of 21 in simple way.

Steps to Learn Table of 21

Let’s see how table of 21 can be written in simple way without craming it

First write as below

21 * 1 =
21 * 2 =
21 * 3 =
21 * 4 =
21 * 5 =
21 * 6 =
21 * 7 =
21 * 8 =
21 * 9 =
21 * 10 =

Now write counting starting from 1-9 and 10.

For 10, just write 0 and keep 1 to be added later, See below

21 * 1 =       1
21 * 2 =       2
21 * 3 =       3
21 * 4 =       4
21 * 5 =       5
21 * 6 =       6
21 * 7 =       7
21 * 8 =       8
21 * 9 =       9
21 * 10 =     0

Now write table of 2 before the counting.

See below that the numbers before the counting is the table of 2

21 * 1 =         21
21 * 2 =         42
21 * 3 =         63
21 * 4 =         84
21 * 5 =      105
21 * 6 =      126
21 * 7 =      147
21 * 8 =      168
21 * 9 =      189
21 * 10 =    210   i.e.( 20 + 1 (remaining as above from 10) =  21)

Isn’t it easy?

Now how to calculate it in memory whenever someone ask you.

-say 21 * 6
Put 6 at last to the result of 2 * 6
i.e. 21 * 6 = (2 * 6)  and 6 = 126

-say 21 * 9
Put 9 at last to the result of 2 * 9
i.e. 21 * 9 = (2 * 9)  and 9 = 189
