Automatic Arithmetic Analyzer

This metallic array of arctech clockwork tumblers and wires is arranged into a thin, angled rectangle that neatly fits in the palm of the hand.

Also known as the autosum, this advanced abacus finds use in many fields, from money-counting accountants, to trajectorycalculating artillerists; arcanoscientific alchemists who must calculate precise measurements, to occult ritualists who need to get the geometry of a magic circle just right.

By pushing the neatly-labeled buttons on this apparatus, the user can perform arithmetic functions: addition, subtraction, multiplication, division, exponential functions, trigonometry, and more. The apparatus can also instantaneously divine the current time and date as per Teykfa’s objective readings, and with the flip of a few fine switches, the rotary tumblers can switch from solving equations to displaying the time and date. Some slightly bulkier models even include a bell and clacker, and can be set with an alarm.

The temple of Ingatan in the Elfaivaran settlemenet Rumah Terakir has the peculiar distinction of being the largest buyer of these devices, and aficionados of the nascent field of ‘computational research’ are flocking there, hoping to develop analyzers of far greater capability
