Trivial confusions

Wikipedia has long articles on Parity of zero and 0.999.... These are completely trivial mathematical points that any 10-year-old should be able to understand. Apparently not.

There are also people who confuse a slash with a backslash. I don't know how. The slash has been in common use for centuries. The backslash is an obscure ascii character.
