Answer 2

The expression you've provided can be simplified as follows:

111111111111111 + 1 - 1 + 11 - 11

When you add 1 and then subtract 1, and also add 11 and then subtract 11, you're effectively canceling those operations out, leaving:

111111111111111

So, the final result is 111,111,111,111,111.
