5 × 1,000 + 2 × 100 + 2 × 10 + 3 × 1 = 5,223. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.

why?
Strength 0.50, confidence "high".
Technology & computing
Push notifications go through a single always-open connection per device rather than each app polling separately. Without that consolidation, always-connected phones would not have been practical.
