Interesting. I always associate "1 + 1 = 1" with idempotency. Here, "1 + 1 + 1 = 1", but "1 + 1 = 0".

I'm not a math whiz, so I'm just stuck with "1 + 1 = 2."

you're wrong. 1 + 1 = 10

Which of course is 0 mod 2.

XOR is a simple operation that shows that behavior.

A simple example where 1 + 1 + 1 = 1 is ℤ₂, i.e. the group of integers modulo 2.
