Where 756 fits
Why 756 is special
Switzerland's code is adjacent to Sweden's, and the two countries are confused often enough that Swiss authorities have produced material addressing it.

Read as powers of two: 512 + 128 + 64 + 32 + 16 + 4 = 756.
In historical numeral systems
Egyptian
7 coils of rope, 5 hobbles, 6 strokes
7 × 100 + 5 × 10 + 6 × 1 = 756. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
1 corner wedge + 2 vertical wedges (sixties place), 3 corner wedges + 6 vertical wedges (units place)
12 × 60 + 36 = 756. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
psi, then nu, then stigma, marked as a numeral
psi-nu-stigma + keraia
psi + 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
tav, then shin, then nun, then vav
tav-shin-nun-vav
tav (400) + shin (300) + nun (50) + vav (6) = 756, written in descending order.
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.

Switzerland's ISO numeric code and calling code. Its adjacency to Sweden in one system and not the other is a reminder that both orderings are conventions.

Geography
756 is Switzerland's ISO numeric code. The confusion between Switzerland and Sweden is common enough to be a recognised nuisance, and their adjacent codes do not help.
