Where 713 fits
Why 713 is special
It is cast rather than wrought because the geometry of a cooled turbine blade cannot be machined from bar in any practical way.

In historical numeral systems
Egyptian
7 coils of rope, 1 hobble, 3 strokes
7 × 100 + 1 × 10 + 3 × 1 = 713. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
1 corner wedge + 1 vertical wedge (sixties place), 5 corner wedges + 3 vertical wedges (units place)
11 × 60 + 53 = 713. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
psi, then iota, then gamma, marked as a numeral
psi-iota-gamma + keraia
psi + iota + gamma written in descending order and added — the letters carry their values wherever they stand, so this is addition, not place value.
Hebrew numerals
tav, then shin, then yod, then gimel
tav-shin-yod-gimel
tav (400) + shin (300) + yod (10) + gimel (3) = 713, written in descending order.
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.
