It is an application with which mathematical operations are carried out, it is an electronic machine with which arithmetic calculations can be made. It originated in ancient times with an instrument called abacus which consisted of a wooden box with parallel bars and balls or beads that moved up and down, an invention of the years 2,000 before our era in Mesopotamia.
Calculators were called to the people of the time who were dedicated to this purpose, to make calculations of everything, today they are electronic and many have a built-in printer, there are different ones due to their complexity and their uses and thus change their purpose, There are the most basic ones that only make simple calculations that with the passage of time have been incorporated into mobile devices or better known as cell phones, since the year 1980. Scientific calculators, as their name indicates, are more complex, because they make trigonometry and statistical calculations based on data already supplied, making a mathematical operation simpler, facilitating the creation of graphs with algebraic components, which solve equations.more complicated that are useful at the financial level, showing a numbering of more than 10 digits. The calculator has undergone great transformations through time, from being a more complicated and large device, to being able to fit in a trouser pocket and having all the complicated applications into something that only fits in the user's hand, and having a complex combination of a large-scale calculator on a computer and performing from comfort much of a job that in the past was done by hand, long and tedious.
