Morphology

positional + notation

The meaning is directly compositional: 'positional' (dependent on position) modifies 'notation' (a system of symbols), so the phrase denotes a system of symbols whose values depend on their position. This modifier+noun pattern is standard and cross-linguistically common, so a B1 learner who knows both constituents can infer the intended meaning.

Etymology

Positional notation comes from the simple idea that where a digit sits, its position, decides its 'value'. Imagine a row of boxes where each box is worth ten times the one on its right; moving a digit left makes it worth more. So positional notation is the way of writing numbers where a digit's place changes what it means.
