The evolution of the scientific calculator

The scientific calculator

Although we may have started out using our fingers and toes for counting, mankind has been busy designing machines to aid with calculationsfor many centuries. From counting devices from the beginning to modern calculators many things have been created in the space between.

Today, students and professionals alike have access to scientific calculators capable of executing complex mathematical functions while also solving equations. They save a huge amount of time, compared to writing out and solving individual problems and equations.

However, how did inventors advance from the very first abacus hundreds of years ago to the modern scientific calculator?

What is a scientific calculator?

Scientific calculators, often referred to as digital calculators are electronic devices that can perform a range of calculations that are used in math, engineering and science.

More basic calculators generally have four main tasks: subtracting, adding multiplying, dividing and adding. Certain advanced electronic calculators come with additional functions such as Instant percentage calculators. Scientific calculators, on the contrary, are capable of solving difficult mathematical problems for example, those used in the fields of statistics or probability.

Many students use scientific calculators for high school and college level instruction in classes like calculus and algebra. They're also frequently used as professional tools by engineers and architects, among others.

In the present, more advanced calculators are on the market. For instance graphing calculators. graphing calculator has all the features of a scientific calculator along with the ability of graphing input data.

The history of the calculator

Early calculators

The first time humans used instruments to count at in the development of abacus, a tool so old its exact origins have never been confirmed. It's a process of moving a group of beads or balls from one side of a row of poles to the other side of the row.

About the middle of 17th century the first machine to add was developed. It was able of subtracting and adding by turning a set of dials.

Then, a series of variations of the adding machine advanced mankind towards the modern electronic calculators of the present. Philip Hahn's circular, hand-cranked calculator in 1778, and the first calculator that was commercially manufactured by Charles Xavier Thomas de Colmar in 1820.

Modern electronic calculators

Back in 1954, IBM released the initial ever all transistor calculator. Prior calculators utilized vacuum tubes to function, but this model used around 3,000 transistors instead. It was a big, bulky machine that could cost up to $83,210.

Pretty soon, inventors began producing smaller versions of the current calculator. In 1967 that first calculator for handheld use appeared on the market. In the years since, the basic interface of standard handheld calculators hasn't been changed in a significant way. It was introduced for sale commercially in the year 1970 It weighed 45 pounds and included ten buttons for numerical values that varied from zero to nine. The display was able of showing numbers up to 12 decimal spaces.

Pocket calculators

Through the 1970s calculators were constantly evolving. First pocket calculator with an LED display was introduced by BUSICOM in 1971 and cost $395. Hewlett-Packard soon followed in 1974 with its first handheld calculator that could be programmable at $795.

In the year 1985, Casio had released the first graphing calculator and immediately began to improve the model. They're one of the most popular brand names of modern scientific calculators as we see them to this day.

The first calculator that was scientific in nature.

Of the many different versions of the modern calculator the one that was released in 1968 Hewlett-Packard HP-9100A can be described as the first scientific calculator. It used transistor logic, CORDIC trigonometry algorithm and was constructed on RPN entry.

Since then, various brands have taken over and controlled the market for scientific calculators, including Sharp, Casio and Canon. Casio is particularly associated with their popular FX series, such as their Casio FX-991EX popularly utilized by students at school.

Modern scientific calculators can be used

Modern scientific calculators are able to perform a basic array of calculations and functions. Different makes and models may have additional features.

Scientific notation

When numbers are too large and long to write using decimal numbers, then scientific notation is often used instead. One example of scientific notation could be "m x 10n."

Arithmetic with floating point floating

This type of numerical representation is often used to deal with very small or very massive numbers. It represents calculations and figures using an approximal formula instead of an ordinary integer.

Trigonometry

Trigonometry includes measuring and finding the angles and angles of triangles relative to one another. It is typically taught as an aspect of geometry within the educational system. Scientific calculators allow you to calculate and display trigonometric ratios and formulas.

Constants

Scientific calculators also include shorthand buttons for constants such as "pi" so you can effortlessly incorporate their use into calculations and formulae.

Calculus

In high school education, calculus includes the study of concepts such as functions and limits. Scientific calculators allow you to solve problems directly, without the need for lengthy, written calculations with pen and the paper.

Fractions

Scientific calculators often display fractions as decimal numbers in default. However, the many functions of a scientific calculator allow you to write things like fractions in a range varieties of formats.

Complex numbers

In some mathematical equations it is possible to use an imaginary number and denoted with "i." Scientific calculators allow you to calculate using complex numbers. These numbers are represented as "a + bi."

The best scientific calculators

A great scientific calculator that is ideal for middle school students
