The stick multiplication tables have been inspired by the work of T K Srinivasan. If you have
two sticks. You can either put them in parallel or you can put them in cross. Now there is
only one junction where they intersect. Now, 1 into 1 is equals to 1 and you can write
1 in the grid like this. Now, you take one more stick and keep it horizontally and one more vertically.
So there are two horizontal and two vertical sticks. If you count the junctions, there
are 1, 2, 3 and 4. So 2 into 2 is equal to 4. And in your grid, you can write 2X2 = 4.
This is how you make a multiplication table. Now you put one more stick vertically so there
will be 3X2 = 6 and you mark 6. If you keep one more horizontal there will be 3X3 would
be 9. Now, 4X3 would be 12.4 horizontal and 3 vertical sticks. And we'll have 12 junctions.
Suppose you take nine sticks horizontally and nine vertically. If you want to count
the junctions. The first horizontal line will be nine. Again 9, 18, 27, 35, 42. So, 9x9 sticks
will generage 81 junctions. And in this grid, under 9 horizontal and nine vertical, you
write 81. So, you can make your own multiplication table. And this is great fun. This is how
you multiply by 0 which is very abstract concept. You can see 2 sticks horizontal and 2 vertical.
And there are 4 jumctions. Now, suppose if I remove 1 vertical stick. Now it is 2X1. There
are just 2 junctions. And 2X1 is 2. Remove the last vertical stick, now there are no
vertical sticks, so 2x0 is 0. Remove one more horizontal stick, there are no vertical sticks,
only one horizontal stick. So, 1X0 is 0. If you remove the last horizontal stick, this is
0X0, no stick into no stick is equal to 0. Now you take a thick card strip, Which will
be equivalent to 10 sticks. Now, if you put a strip on a strip, this will be equivalent
to 10X10, so the junction will be equivalent to 100. Now, we are going to do 2 digit multiplication.
So, vertically this is 10 plus 2. So it is 12. So, the strip on stick is 10. Now you are going to keep three sticks
horizontally. So, the horizontal number would be 13. Now we are going to see the multiplication.
Now if you look at the strip, this is 13 and the vertical is 10, 11, 12. Now, this junction
of strip on strip is 100. Strip on stick is 10. This is another 10. Now we keep adding
100, 110, 120, 130, 140, 150, 151, 152, 153, 154, 155, 156. Now the multiplication you
can see very clearly. It is 156.
