CCXCVIII uses the subtractive pair XC: ten before a hundred — a hundred minus ten.
Binary
1 0 0 1 0 1 0 1 0
1 × 256 + 0 × 128 + 0 × 64 + 1 × 32 + 0 × 16 + 1 × 8 + 0 × 4 + 1 × 2 + 0 × 1 = 298
Octal

4 × 64 + 5 × 8 + 2 × 1 = 298
Hexadecimal
1 2 a
1 × 256 + 2 × 16 + a × 1 = 298
Read as powers of two: 256 + 32 + 8 + 2 = 298.
In historical numeral systems
Egyptian
2 coils of rope, 9 hobbles, 8 strokes
2 × 100 + 9 × 10 + 8 × 1 = 298. 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), 5 corner wedges + 8 vertical wedges (units place)
4 × 60 + 58 = 298. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
sigma, then koppa, then eta, marked as a numeral
sigma-koppa-eta + keraia
sigma + koppa + 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 tsadi, then het
resh-tsadi-het
resh (200) + tsadi (90) + het (8) = 298, written in descending order.
Maya
2 bars + 4 dots (upper, twenties place) over 3 bars + 3 dots (lower, units place)
14 × 20 + 18 = 298. 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.
