There are only two places on Earth that refuse to use the "+" sign in math because it looks too much like a Christian cross.
• Israel, which uses "﬩" instead
• ISIS-controlled territories, which use "z" instead
Just Israel and ISIS. That's the whole list.
A genuinely wild fact about religious symbol anxiety in math that puts Israel and ISIS in the same sentence for good reason.
