"Abacus is a Latin term applied to an apparatus used by the Chinese for facilitating arithmetical operations, consisting of a number of parallel cords or wires, upon which balls or beads are strung, the uppermost wire being appropriated to units, the next to tens, &c.-In classic architecture it denotes the tablet forming the upper member of a column, and supporting the entablature. In Gothic architecture the upper member of a column from which the arch springs."—(Charles Leonard-Stuart, 1911)

A calculator that performs simple arithmetic functions

This machine is used for multiplication, and division purposes. Multiplication is the mathematical operation of scaling one number by another. It is one of the four basic operations in elementary arithmetic. Conceptually, division describes two distinct but related settings. Partitioning involves taking a set of size a and forming b groups that are equal in size. The size of each group formed, c, is the quotient of a and b. Quantitate division involves taking a set of size a and forming groups of size b. The number of groups of this size that can be formed, c, is the quotient of a and b

A typewriter is a mechanical or electromechanical device with a set of "keys" that, when pressed, cause characters to be printed on a medium, usually paper. From their invention before 1870 through much of the 20th century, typewriters were indispensable tools for many professional writers and in business offices. By the end of the 1980s, word processor applications on personal computers had largely replaced the tasks previously accomplished with typewriters. Typewriters, however, remain popular in the developing world and among some niche markets, and for some office tasks.
