dextrâ ad sinistram, nempe 8, primo enim numero seriei continuæ subjacet unitas. Quare ponatur ille 8, primus character semel...........................................................................................8.
Secundus, qui est 7, ter sumatur, seu per 3 multiplicetur, secundo enim numero seriei subjacet 3, sitque productus...........21.
Tertius bis sumatur, subjacet enim 2 ipsi 3, quare tertius character qui est 1, per 2 multiplicatus, sit...................................2.
Quartus eâdem ratione per 6 multiplicatus............................12.
Quintus per 4 multiplicatus....................................................16.
Sextus per 5 multiplicatus......................................................25.
Septimus semel, septimo enim subjacet 1.............................7.
Octavus ter sumptus.............................................................24.
Nonus bis sumptus................................................................4.
____
Et sic deinceps si superessent. Jungantur hi numeri............119.
Si ipse aggregatus 119 est multiplex ipsius 7, numerus quoque propositus, 287642178, ejusdem 7 multiplex erit.
Potest autem dignosci eâdem methodo, utrum ipse 119 sit multiplex 7, scilicet sumendo semel primum characterem............9.
secundum characterem ter....................................................3.
et præcedentem bis...............................................................2.____
14.
Si enim summa 14 est multiplex 7, erit et 119 ejusdem multiplex.
