A compass, also commonly known as a pair of compasses, is a technical drawing instrument that can be used for inscribing circles or arcs. As dividers, it can also be used as a tool to mark out distances, in particular, on maps. Compasses can be used for mathematics, drafting, navigation and other purposes.

The Construction and Principal Uses of Mathematical Instruments (French: Traité de la construction et des principaux usages des instrumens de mathématique) is a book by Nicholas Bion, first published in 1709. [1] It was translated into English in 1723 by Edmund Stone. [2] The book describes ways to construct mathematical instruments.
Military instruments as a class draw on most of the categories of instrument described throughout this article, such as navigation, astronomy, optics, and imaging, and the kinetics of moving objects. Common abstract themes that unite military instruments are seeing into the distance, seeing in the dark, knowing an object's geographic location ...
Bi-quinary coded decimal-like abacus representing 1,352,964,708. An abacus (pl. abaci or abacuses), also called a counting frame, is a hand-operated calculating tool which was used from ancient times in the ancient Near East, Europe, China, and Russia, until the adoption of the Hindu–Arabic numeral system.

Protractors have been used to measure and draw angles and arcs of a circle accurately since about the 13th century, [1] although mathematics and science demanded more detailed drawing instruments. The adjustable corner ruler was developed in the 17th century, but a feasible screw-tightened version not until the 1920s.
