What is a calculator?
A calculator (or pocket computer) is an electronic or digital device designed to perform calculations.
Today’s calculator has been preceded by quite a few interesting developments.
The first was the abacus, which was developed around 2000 BC.
Then the mechanical calculator was invented in the 17th century, and over the years it has evolved into more advanced calculators.
The first electronic calculator was created in 1960, and its size was not small at all – bigger than a new personal computer.
Pocket calculators were invented a decade later in the 1970s, following advances in technology in the chip industry, led by the development of the first computer chip – the Intel 4004, and were at first very expensive.
The technological advances at the early 1980s made calculators cheaper and cheaper until they became available in schools around the world.
In recent decades, the use of electronic calculators has declined in favor of digital calculators, which have become increasingly common with the expansion of the use of personal computers, tablets and mobile phones, and their share of computing devices in the world dropped from 41 percent in 1986 to less than 0.05 percent in 2007.
Today, calculators are used mainly to solve simple computational problems that do not require computer use, and is more common among pupils and students.
Types of calculators
In addition to the basic calculator used for a wide range of purposes, a wide variety of calculators for specific fields have been developed over the years.
The most popular of these calculators are the scientific calculator, the financial calculator and the graphic calculator.
How do I use the calculator?
In order to make a calculation using our calculator, you can use the computer keyboard to type numbers or click on them with your mouse.
Deleting typing can be done using the Backspace key or using the arrow key on the calculator’s own keypad.
In addition, this calculator can also perform more complex calculations – exponents, square root and more.
