Morphology
Although 'number system' is transparent, the modifier 'sexadecimal' is a rare/technical form and not built from familiar, predictable morphemes for a B1 learner (and may be confused with 'hexadecimal' or 'sexagesimal'). The crucial meaning (base‑16) is not reliably derivable from the constituent words, so the overall expression is opaque to an average B1 learner.
Etymology
Sexadecimal number system may come from joining the Latin word sex ('six') and decimal ('ten'), which gives the idea 'six plus ten' meaning 'sixteen'. So it refers to a way of counting that uses sixteen different symbols, like 0 to 9 and A to F.
