History of Calculators The history of calculators dates back to the abacus, which was invented in ancient times and used for simple arithmetic calculations. In the 17th century, mechanical calculators were invented, which used gears, levers, and other mechanical components to perform calculations. These calculators were primarily used by scientists, mathematicians, and engineers for complex mathematical computations.

The first electronic calculator was invented in the 1960s, which revolutionized the way people performed calculations. These calculators were small, portable, and could perform complex calculations quickly and accurately. Since then, calculators have evolved significantly, and today we have a wide range of calculators available for different purposes.

Types of Calculators There are several types of calculators available in the market today, each with its own set of features and functions. Some of the most common types of calculators include:
