Can you guys explain how to find the sum of the two digit multiples of 11??

I'm not sure I understand the question.

The 2-digit multiples of 11 are  11,  22,  33,  44,  55,  66,  77,  88, and  99 .

Another, easier and slightly slicker, way to do it would be to factor the list
first, and then do the sum as:

       11 (1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9)  =  11 x 45
