Where 356 fits
Why 356 is special
Malta is among the smallest EU states by area and one of the most densely populated countries in the world. Its numbering plan has no area codes at all, which is practical only at that scale.
Same number, different meanings
How 356 is understood across different contexts — never implying one meaning because of another.
- Mathematics
Malta is among the smallest EU states by area and one of the most densely populated countries in the world. Its numbering plan has no area codes at all, which is practical only at that scale.
- Technology & computing
A356 is a cast aluminium-silicon-magnesium alloy with good fluidity and pressure tightness, used for wheels, cylinder heads and structural castings.
- Geography
+356 reaches Malta, which has no internal area codes — every number is dialled the same way from anywhere in the country. That is feasible only for a state small enough not to need geographic routing.

Binary
1 0 1 1 0 0 1 0 0
1 × 256 + 0 × 128 + 1 × 64 + 1 × 32 + 0 × 16 + 0 × 8 + 1 × 4 + 0 × 2 + 0 × 1 = 356
Octal
5 4 4
5 × 64 + 4 × 8 + 4 × 1 = 356
Hexadecimal
1 6 4
1 × 256 + 6 × 16 + 4 × 1 = 356
Read as powers of two: 256 + 64 + 32 + 4 = 356.
In historical numeral systems
Egyptian
3 coils of rope, 5 hobbles, 6 strokes
3 × 100 + 5 × 10 + 6 × 1 = 356. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
5 vertical wedges (sixties place), 5 corner wedges + 6 vertical wedges (units place)
5 × 60 + 56 = 356. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
tau, then nu, then stigma, marked as a numeral
tau-nu-stigma + keraia
tau + nu + stigma written in descending order and added — the letters carry their values wherever they stand, so this is addition, not place value.
Hebrew numerals
shin, then nun, then vav
shin-nun-vav
shin (300) + nun (50) + vav (6) = 356, written in descending order.
Maya
3 bars + 2 dots (upper, twenties place) over 3 bars + 1 dot (lower, units place)
17 × 20 + 16 = 356. Places stack vertically with the smallest at the bottom, so the upper group is worth twenty times the lower.
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.
