Why 248 is special
Seychelles has the smallest population of any African state, spread across 115 islands. Its economy depends on tourism and tuna, both vulnerable to conditions it does not control.

CCXLVIII uses the subtractive pair XL: ten before fifty — fifty minus ten.
Binary
1 1 1 1 1 0 0 0
1 × 128 + 1 × 64 + 1 × 32 + 1 × 16 + 1 × 8 + 0 × 4 + 0 × 2 + 0 × 1 = 248
Octal

3 × 64 + 7 × 8 + 0 × 1 = 248
Hexadecimal

f × 16 + 8 × 1 = 248
Read as powers of two: 128 + 64 + 32 + 16 + 8 = 248.
In historical numeral systems
Egyptian
2 coils of rope, 4 hobbles, 8 strokes
2 × 100 + 4 × 10 + 8 × 1 = 248. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
4 vertical wedges (sixties place), 8 vertical wedges (units place)
4 × 60 + 8 = 248. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
sigma, then mu, then eta, marked as a numeral
sigma-mu-eta + keraia
sigma + mu + eta 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 mem, then het
resh-mem-het
resh (200) + mem (40) + het (8) = 248, written in descending order.
Maya
2 bars + 2 dots (upper, twenties place) over 1 bar + 3 dots (lower, units place)
12 × 20 + 8 = 248. 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.
