To facilitate their mathematical calculations, people have come up with calculators. Perhaps almost everyone uses this device today. However, despite the fact that it is very popular and accessible, not everyone knows all of its functions. Let us first tell you what is meant by this concept.
This is a special device that performs actions on numbers. Earlier, when the progress of microprocessor and computer technology was not as obvious as it is now, people used hand-held devices or devices (various abacus, slide rule, tables of logarithms). Now, depending on the scope of use, calculators are divided into several types:
Accounting
Engineering
Simple
Financial
Also, now there are a large number of calculators that calculate complex calculations using the program embedded in it (programmed calculator). These types of calculators are used only in a narrow field of activity, for example, in medicine. In the form of typical calculators in this area, you can hardly see anywhere, however, in the form of specialized programs installed on a computer, you can find.
It is clear that before using a calculator, especially an engineering one, you need to pay attention to its structure. As with all calculators, engineering has many buttons and an LCD screen. All this is in one building.
