I've always wondered why some people write 101 at the end of sentences. It seems to be something North Americans do, but I've never really understood what it's supposed to indicate.
It's a college thing. The course number for classes that introduce a subject to the students are/were SUBJ101, where SUBJ is the department/field of study, e.g., MUSC101 could be intro to music.
