Angola is the second-largest Portuguese-speaking country by population after Brazil, a legacy of colonial rule that ended in 1975 after fourteen years of war.
Same number, different meanings
How 244 is understood across different contexts — never implying one meaning because of another.
- Mathematics
Angola is the second-largest Portuguese-speaking country by population after Brazil, a legacy of colonial rule that ended in 1975 after fourteen years of war.
- Geography
+244 reaches Angola. It has more Portuguese speakers than Portugal, which is true of Brazil, Angola and Mozambique alike and reflects where the language actually lives.
- Media & popular culture
BWV 244 was largely forgotten until Mendelssohn revived it in 1829, a performance generally credited with beginning the modern reception of Bach.

CCXLIV uses the subtractive pair IV: one before five — five minus one.
Binary
1 1 1 1 0 1 0 0
1 × 128 + 1 × 64 + 1 × 32 + 1 × 16 + 0 × 8 + 1 × 4 + 0 × 2 + 0 × 1 = 244

f × 16 + 4 × 1 = 244
Read as powers of two: 128 + 64 + 32 + 16 + 4 = 244.
In historical numeral systems
Egyptian
2 coils of rope, 4 hobbles, 4 strokes
2 × 100 + 4 × 10 + 4 × 1 = 244. 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), 4 vertical wedges (units place)
4 × 60 + 4 = 244. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
sigma, then mu, then delta, marked as a numeral
sigma-mu-delta + keraia
sigma + mu + 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 mem, then dalet
resh-mem-dalet
resh (200) + mem (40) + dalet (4) = 244, written in descending order.
Maya
2 bars + 2 dots (upper, twenties place) over 4 dots (lower, units place)
12 × 20 + 4 = 244. 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.
