History of Calculators
Mechanical calculators emerged in the 17th century, with devices like Pascal’s arithmetic machine performing additions through gear rotations. Merchants adopted them for trade balances, reducing manual errors in ledgers. By the 19th century, comptometers sped multiplications, revolutionizing accounting offices nationwide.
Electronic versions arrived mid-20th century, powered by vacuum tubes for faster operations. Desktop models dominated corporate desks, handling payrolls and inventories efficiently. The 1970s introduced handheld units with LED displays, making computations portable for field engineers and sales teams.
Programmable calculators in the 1980s integrated memory functions, enabling custom formulas. Personal computers expanded capabilities, birthing spreadsheet-based tools. Internet eras democratized access, evolving calculators into web apps with real-time data feeds.
