the Abacus
This originated in the Mesopotamian period
Consisted of a table with columns ordered successively, which represented the order by magnitude of the number system sexagesimal they had. -
Period: 150 BCE to 100 BCE
Anticipate mechanism
From ancient Greece
Considered the first mechanical analogue computer
Used to predict astronomical positions and eclipses up to nineteen years for astrological and calendrical purposes, 5 6 7 and also predict the exact date of six ancient Greek contests -
Period: to
slide rule
Easy to use to divide and multiply, dominated between those who needed to perform operations of logarithms, logarithmic tables -
Period: to
Clock calculator
The first machine that could add and subtract numbers up to six digits, a large device full of levers created by Wilhelm Schickard in Germany -
Period: to
Pascaline
Developed by Blaise Pascal in France.
Pascal began to think of this apparatus after his father was assigned the task of reorganizing tax revenues in the French province of Haute-Normandie, creating a device that could add, subtract, multiply and divide.
The launch of the Pascalina began the development of mechanical calculators in Europe and the world, a development that three centuries later would enable the creation of the microprocessor, first developed for a calculator in 1971. -

Calculator user interface
The American James L. Dalton made one of the biggest innovations, inserting buttons instead of levers. -
Period: to
Short calculator
Appeared in Vienna, Austria
Although it was quite expensive, it became a hit because of its portability. The mechanical calculator had a really compact design, which fit in one hand, and allowed to add, subtract, multiply and divide. -

IBM and Casio model 14-A
In 1954, IBM introduced a large transistor-based calculator, and in 1957 launched the first fully electronic commercial calculator, called the IBM 608.
Casio in Japan, was launching its model 14-A calculator that is cataloged as the first relatively compact electrical calculator (it was installed inside a desk). I say electrical and not electronic because it was based on a relay and not on a logic board. -

Sumlock Comptometer ANITA
Is the first 100% electronic calculator made by British Bell Punch. This calculator used vacuum tubes, cold cathode tubes and decatrons in its circuits, plus 12 "Nixie" tubes as a screen. -

Portable calculators
These used rechargeable batteries. The first portable calculators appeared in Japan that year, and were quickly sold around the world. Some of these equipment were the Sanyo ICC-0081, Canon Pocketronic and Sharp QT.8B -

Calculator on a chip
The Mostek MK6010, followed by a Texas Instruments model that same year. From then on this became the model for calculators around the world. Although these first portable calculators were very expensive, with the passage of time the advances in electronics along with the technologies of screens (fluorescent, LED and LCD) would make in just a few years the prices would be accessible for many. -

scientific calculator
Texas Instruments launched the first scientific calculator, the SR-10, which cost US $ 150 and included a button for "π" (pi). In the following years logarithmic functions, trigonometry and others were added. -

Financial calculators
Financial calculators have appeared, and since then they have continued their development to be emulated almost everywhere, allowing us today to take advantage of this invention in almost any electronic device, from a clock to a telephone.
