Terminology that isn't taught in the schools any more
On this extra credit assignment the students were told to draw a pedigree, numbering generations with Roman numerals and individuals with Arabic numbers. One student came to office hours to confirm what was meant by Arabic numbers, and near the top of the pile of assignments that I'm grading I've already found one numbered "١,٢,٣..." and not by someone with an Arabic name either, so they probably had to put in a little extra effort to find these "Arabic numbers."
