hexadecimal + number + system
The phrase is transparently compositional: 'hexadecimal' specifies the base-16 notation and it modifies 'number system', so the combined meaning is simply a system of numbers using base sixteen. A B1 learner who knows the constituent words (and the meaning of 'hexadecimal') can reliably infer the MWE meaning without prior exposure.
Etymology
The term hexadecimal number system comes from combining hex meaning 'six' and decimal meaning 'ten', so think of 'six' plus 'ten' to make sixteen. That's why the name refers to a number system with sixteen values, written 0–9 and A–F.
