Where 152 fits
Why 152 is special
It exists because the four-seat 172 was more aircraft than a student needed, and a great many pilots have made their first solo flight in one.

Read as powers of two: 128 + 16 + 8 = 152.
In historical numeral systems
Egyptian
1 coil of rope, 5 hobbles, 2 strokes
1 × 100 + 5 × 10 + 2 × 1 = 152. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
2 vertical wedges (sixties place), 3 corner wedges + 2 vertical wedges (units place)
2 × 60 + 32 = 152. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
rho, then nu, then beta, marked as a numeral
rho-nu-beta + keraia
rho + nu + beta written in descending order and added — the letters carry their values wherever they stand, so this is addition, not place value.
Hebrew numerals
qof, then nun, then bet
qof-nun-bet
qof (100) + nun (50) + bet (2) = 152, written in descending order.
Maya
1 bar + 2 dots (upper, twenties place) over 2 bars + 2 dots (lower, units place)
7 × 20 + 12 = 152. 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.
