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 HP-35, introduced on February 1, 1972, was Hewlett-Packard's first pocket calculator and the world's first handheld scientific calculator. [7] Like some of HP's desktop calculators it used RPN. Introduced at US$395, the HP-35 was available from 1972 to 1975.
Hyphenate all numbers under 100 that need more than one word. For example, $73 is written as “seventy-three,” and the words for $43.50 are “Forty-three and 50/100.” You don’t need to ...
One-to-one correspondence, [2] a rule to count how many items, e.g. on a tally stick, eventually abstracted into numbers. Comparison to a standard, [3] a method for assuming reproducibility in a measurement, for example, the number of coins. The 3-4-5 right triangle was a device for assuring a right angle, using ropes with 12 evenly spaced ...

The Wang LOCI-2 [11] [12] [13] (Logarithmic Computing Instrument) desktop calculator [14] (the earlier LOCI-1 [15] in September 1964 was not a real product) was introduced in January 1965. Using factor combining , it was the first desktop calculator capable of computing logarithms , which was quite an achievement for a machine without any ...
