Made in Japan, this was also the first calculator to use an LED display, the first hand-held calculator to use a single integrated circuit (then proclaimed as a "calculator on a chip"), the Mostek MK6010, and the first electronic calculator to run off replaceable batteries. Using four AA-size cells the LE-120A measures 4.9 by 2.8 by 0.9 inches ...
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 original's computing section included four pages explaining the workings and the distinctions between a calculator and a general-purpose computer, and four pages on binary arithmetic, logical AND and OR gates, and how these are assembled into a half adder and full adder; these were replaced with entirely new art and more detailed ...
The HP-16C Computer Scientist is a programmable pocket calculator that was produced by Hewlett-Packard between 1982 and 1989. It was specifically designed for use by computer programmers, to assist in debugging. It is a member of the HP Voyager series of programmable calculators. It was the only programmer's calculator ever produced by HP ...
How to Solve It suggests the following steps when solving a mathematical problem: . First, you have to understand the problem. [2]After understanding, make a plan. [3]Carry out the plan.
In some areas of study and professions scientific calculators have been replaced by graphing calculators and financial calculators which have the capabilities of a scientific calculator along with the capability to graph input data and functions, as well as by numerical computing, computer algebra, statistical, and spreadsheet software packages ...
The mathematical operations used in the book are subtraction, addition, multiplication, division and trigonometric functions. Angles are illustrated in degrees and not radians. The calculations are carried out on a calculator. The book "explains in simpler terms the equations used to calculate almanac data." [3]
The term "computer", in use from the early 17th century (the first known written reference dates from 1613), [1] meant "one who computes": a person performing mathematical calculations, before electronic calculators became available.
