Where 234 fits
Why 234 is special
The 2x block covers Africa. Nigeria has the largest telephone network on the continent, and its mobile networks grew so much faster than its fixed lines that the fixed network is now a rounding error by comparison.

CCXXXIV uses the subtractive pair IV: one before five — five minus one.
Binary

e × 16 + a × 1 = 234
Read as powers of two: 128 + 64 + 32 + 8 + 2 = 234.
In historical numeral systems
Egyptian
2 coils of rope, 3 hobbles, 4 strokes
2 × 100 + 3 × 10 + 4 × 1 = 234. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
3 vertical wedges (sixties place), 5 corner wedges + 4 vertical wedges (units place)
3 × 60 + 54 = 234. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
sigma, then lambda, then delta, marked as a numeral
sigma-lambda-delta + keraia
sigma + lambda + delta written in descending order and added — the letters carry their values wherever they stand, so this is addition, not place value.
Hebrew numerals
resh, then lamed, then dalet
resh-lamed-dalet
resh (200) + lamed (30) + dalet (4) = 234, written in descending order.
Maya
2 bars + 1 dot (upper, twenties place) over 2 bars + 4 dots (lower, units place)
11 × 20 + 14 = 234. 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.

+234 reaches Nigeria, which has the largest telephone network in Africa. Its mobile networks expanded so much faster than its fixed lines that the fixed network is now negligible by comparison — a pattern repeated across much of the continent.
