Morphology

number + system

The meaning 'a system or notation for representing numbers' is directly and compositionally derived from 'number' (numerical value) + 'system' (a structured set of rules), so a learner who knows both words can infer the phrase. This noun-noun compound follows a common, cross-linguistically transparent pattern (e.g. Spanish 'sistema de numeración'), making it readily understandable at B1.

Etymology

Number system comes from the simple idea of combining number, meaning 'a count', and system, meaning 'a set of rules', when people used marks, pebbles or fingers to show amounts. So number system now means 'a way or set of rules for writing and working with numbers'.
