Abacus-based mental calculation (AMC), which was derived from the abacus, is the act of performing calculations, including addition, subtraction, multiplication, and division, in the mind by manipulating an imagined abacus. It is a high-level cognitive skill that runs calculations with an effective algorithm.
In Early English work, the abacus is generally circular, and in larger work, a group of circles (fig. 4), with some examples of octagonal and square shapes. The mouldings are generally half-rounds, which overhang deep hollows in the capital. In France, the abacus in early work is generally square, as at Chateau de Blois (fig. 3).
Abacus – The Aztec and Maya of Mesoamerica performed arithmetic operations using an abacus. It served as a more accurate and faster alternative to a written solution or relying on memory. Archaeologists have recorded the Mesoamerican abacus, or Nepohualtzintzin, as being present in Mesoamerica from at least between 900 and 1000 CE. [1]
This example is missing many counter beads. Velser's reconstruction of Roman abacus (ca. 1600) The Ancient Romans developed the Roman hand abacus , a portable, but less capable, base-10 version of earlier abacuses like those that were used by the Greeks and Babylonians .
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. The soroban is composed of an odd number of columns or rods, each having beads: one separate bead having a value of five, called go-dama (五玉, ごだま, "five-bead") and four beads each having a value of one, called ichi-dama (一玉, いちだま ...
The book describes methods of doing calculations without aid of an abacus, and as Ore (1948) confirms, for centuries after its publication the algorismists (followers of the style of calculation demonstrated in Liber Abaci) remained in conflict with the abacists (traditionalists who continued to use the abacus in conjunction with Roman numerals).
An abacus. Instead, mathematical progress became focused on computational tools. In 15 century, abacus came into its suan pan form. Easy to use and carry, both fast and accurate, it rapidly overtook rod calculus as the preferred form of computation. Zhusuan, the arithmetic calculation through abacus, inspired multiple new works.
Abaqus FEA [4] [5] (formerly ABAQUS) is a software suite for finite element analysis and computer-aided engineering, originally released in 1978.The name and logo of this software are based on the abacus calculation tool. [6]
