Another example

So,here is another example of multiplications using strings of 1.
1 2 3 4 5 6 7 8 9* 1 1 1 1 1 [here we have 5 ones]

1 2 3 4 5 6 7 8 9
* 1 1 1 1 1
---------------------------------------------------------------------------------------------
9 [putting the LMD ]
7 [adding the two LMDs,8+9=17,put 7,carry1]
5 [7+8+9=24+1(carry)=25,put 5,carry 2]
2 [6+7+8+9+2(carry)=32,put 2 carry 3]
8 [5+6+7+8+9+3(carry)=38,put 8 carry 3]
3 [5 digits has been added,so leaving out 9 to take
4,4+5+6+7+8+3(carry)
=33,put 3 carry]
8 [leaving 8 to take 3,3+4+5+6+7+3(carry)=28,put 8,
carry 2]
2 [2+3+4+5+6+2(carry)=22,put 2,carry 2]
7 [1+2+3+4+5+2(carry)
=17,put 7,carry 1]
1 [1+2+3+4+1(carry)=11,put 1,carry 1]
7 [1+2+3+1(carry)=7]
3 [2+1=3]
1

So,this is the method to multiply any number with a string of 1's.Try it.Bye.

hey, i didnt even know tat u r carryin of such fantastic maths work here...though i confess that i haven't gone thru da procedures, i likd da idea immensely.
