  2. Roman abacus - Wikipedia

    en.wikipedia.org/wiki/Roman_abacus

    The longer slot with five beads below the Ө position allowed for the counting of 1/12 of a whole unit called an uncia (from which the English words inch and ounce are derived), making the abacus useful for Roman measures and Roman currency. The first column was either a single slot with 4 beads or 3 slots with one, one and two beads ...

    The Song dynasty and earlier used the 1:4 type or four-beads abacus similar to the modern abacus including the shape of the beads commonly known as Japanese-style abacus. [30] In the early Ming dynasty, the abacus began to appear in a 1:5 ratio. The upper deck had one bead and the bottom had five beads. [31]

    en.wikipedia.org/wiki/Soroban

    A suanpan (top) and a soroban (bottom). The two abaci seen here are of standard size and have thirteen rods each. Another variant of soroban.

  5. Doric order - Wikipedia

    en.wikipedia.org/wiki/Doric_order

    Crown moldings soften transitions between frieze and cornice and emphasize the upper edge of the abacus, which is the upper part of the capital. Roman Doric columns also have moldings at their bases and stand on low square pads or are even raised on plinths. In the Roman Doric mode, columns are not usually fluted; indeed, fluting is rare.

  6. Suanpan - Wikipedia

    en.wikipedia.org/wiki/Suanpan

    The suanpan is a 2:5 abacus: two heaven beads and five earth beads. If one compares the suanpan to the soroban which is a 1:4 abacus, one might think there are two "extra" beads in each column. In fact, to represent decimal numbers and add or subtract such numbers, one strictly needs only one upper bead and four lower beads on each column.
