The Algebra FX 2.0 versions have symbolic algebra, while the FX 1.0 versions lack this. There are community written tools for accessing the ROM-DOS operating system thus allowing C and Pascal compilers to be used. Models: Algebra FX 2.0, FX 1.0, Algebra FX 2.0 Plus, FX 1.0 Plus (French versions: Graph 100, Graph 100+)
A simple arithmetic calculator was first included with Windows 1.0. [5]In Windows 3.0, a scientific mode was added, which included exponents and roots, logarithms, factorial-based functions, trigonometry (supports radian, degree and gradians angles), base conversions (2, 8, 10, 16), logic operations, statistical functions such as single variable statistics and linear regression.
The first American-made pocket-sized calculator, the Bowmar 901B (popularly termed The Bowmar Brain), measuring 5.2 by 3.0 by 1.5 inches (132 mm × 76 mm × 38 mm), came out in the Autumn of 1971, with four functions and an eight-digit red LED display, for US$240, while in August 1972 the four-function Sinclair Executive became the first ...
The model featured a 5×6-dot LCD matrix cells on the top line of the screen and a 7-segment LCD on the bottom line of the screen that had been used in Casio fx-4500P programmable calculators. [1] The S-V.P.A.M. system was also used in the other W series models and also the MS series of calculators that followed.
The Curta was conceived by Curt Herzstark in the 1930s in Vienna, Austria.By 1938, he had filed a key patent, covering his complemented stepped drum. [3] [4] This single drum replaced the multiple drums, typically around 10 or so, of contemporary calculators, and it enabled not only addition, but subtraction through nines complement math, essentially subtracting by adding.
The TI-84 Plus C Silver Edition was released in 2013 as the first Z80-based Texas Instruments graphing calculator with a color screen.It had a 320×240-pixel full-color screen, a modified version of the TI-84 Plus's 2.55MP operating system, a removable 1200 mAh rechargeable lithium-ion battery, and keystroke compatibility with existing math and programming tools.

Qlik's Associative Engine lets users do big data analytics, combining a number of data sources so that associations and connections can be formed across the data. [59] [60] The two main data analytics products, [61] [62] Qlik Sense (current cloud-based software) and QlikView (legacy on-premise product), serve different purposes running on the same engine.
Such software calculators first emerged in the 1980s as part of the original Macintosh operating system and the Windows operating system (Windows 1.0). Some software calculators directly simulate one of the hardware calculators, by presenting an image that looks like the calculator, and by providing the same functionality.
