🕰️ A Brief History of Calculators
The calculator has evolved from simple manual tools to sophisticated electronic devices. Early methods included the abacus used in ancient China and Mesopotamia. In the 17th century, inventors like Pascal and Leibniz developed mechanical calculators. The 19th century saw Charles Babbage design programmable machines. By the mid-20th century, electromechanical and then fully electronic calculators became widespread. In the 1970s, microprocessors enabled the creation of portable calculators. Today, calculators exist as apps and integrated software on digital platforms.
