How to learn tables of maths

For learning tables from 1 to 100.
First of all , you learn tables from 1 to 20 by heart.
If we suddenly ask 18 * 6 then you quickly say 108

Now for learning tables that ends with the digit 0
Ex - 10,20,30,40,50…and more

You can easily say (not write because we want learning not writing)

Next for learning tables that ends with the digit 1
Ex- 11,21,31,41,51,61…

We will say the table of first digit and and simply put the digit that how many times we multiplied
ex- 61 * 4 = 244 ( last digit - 4 times multiplied)

41 * 1 = 41
41 * 2 = 82
41 * 3 = 123
41 * 4 = 164
41 * 5 = 205
41 * 6 = 246
41 * 7 = 287
41 * 8 = 328
41 * 9 = 369
41 * 10 = 410

For learning tables that digits are same
Ex - 11 , 22 ,33 , 44 , 55 , 66…

33 * 5 = 165 (we easily do in mind when we say the table of 33 . For this first we calculate 3 * 5
and then multiplied by 11 quickly.

Special method for learning table of 99
99 * 1 = 99
99 * 2 = 198
99 * 3 = 297
99 * 4 = 396
We easily say this by the table of 9 and put
them 9 in all the places between them.

For learning tables of composite numbers like
24 , 36, 32
We simply say the table of half of this and double it
Ex - table of 36
We say table of 18 and double it.
36 * 4 = 18 four’s are 72 so double is 144

Table of prime numbers ( this contain special method for learning every prime numbers so I am describe it here)
