Question:
Someone in my algebra 2 class thinks that 2 = 0. I was wondering if that
would be true in any of the number systems.

Replies:
Sure, a binary number system modulo 2.

I do not think jlu means "binary" in his answer. One writes "2 = 0 (mod 2)"
where an equal sign with three lines is used instead of the regular equal
sign that I have typed. Is modular arithmetic taught to algebra 2 students?

When I first saw this question, I thought it might be a reference to
something similar to the "2 = 1" pseudoproof.
