here is the trick...
When always multiplying a large number by 11, the last number will always be the last number of the sum we are multiplying.
Let me explain.
176 is the number we are multiplying.
So the last number in out answer will be 6. If the sum was 143 the last number in our answer would be 3... get it?
So now what?
Easy, just add the next number to the last number, 7 + 6 = 13
So the next last number will be 3, carry the 1.
Add the 7 and 1 together, giving 8, then add the carried 1, 9 then write that number as our next part of the answer, 936

Then, the last number will be the first number in our sum, in this case 1.
So the answer is 1936.
you see its very simple...
