TABLES CAN BE REVERSED
The table of 1089 is VERY easy to remember.
1089*1=1089 reverse the digits 9801=1089*9
1089*2=2178 ............................... 8712=1089*8
1089*3=3267 ................................ 7623=1089*7
1089*4=4356 ................................. 6534=1089*6
.....................1089*5=5445 ....................
And the same goes for the table of 9
9*1=09..........90=9*10
9*2=18...........81=9*9
9*3=27 ...........72=9*8
9*4=36............63=9*7
9*5=45............54=9*6
1089*1=1089 reverse the digits 9801=1089*9
1089*2=2178 ............................... 8712=1089*8
1089*3=3267 ................................ 7623=1089*7
1089*4=4356 ................................. 6534=1089*6
.....................1089*5=5445 ....................
And the same goes for the table of 9
9*1=09..........90=9*10
9*2=18...........81=9*9
9*3=27 ...........72=9*8
9*4=36............63=9*7
9*5=45............54=9*6

nice one
now i can easily remember the table of 9
u figured it out yourself or what??
Hey its great to see such a simple way for such a huge number. i can also remember this table easily
Well, I was looking through one of the really really old Shakuntala Devi Books I have. And I came across this trick
For table of 19, first write odd numbers starting from 1 to 19 vertically, then place 9, 8, 7, 6, 5, 4, 3, 2, 1, 0 in every row i.e. 9 by the side of 1; 8 by the side of 3 and so on. And you have finally the table of 19.
1 9
3 8
5 7
7 6
9 5
11 4
13 3
15 2
17 1
19 0
