From ancient abacuses to modern-day supercomputers, humans have continuously sought tools to aid them in complex calculations. The invention of the calculator marks a significant milestone in this quest, revolutionizing the way we perform mathematical operations. Let’s embark on a journey through time to trace the fascinating history of calculators.

The first mechanical calculators, such as the abacus, emerged in ancient civilizations. The abacus, with its beads sliding on rods, allowed for simple arithmetic operations. Later, in the 17th century, the invention of the slide rule brought greater precision to calculations, particularly in scientific and engineering fields.

The 19th and 20th centuries witnessed a rapid advancement in calculating technology, leading to the development of more sophisticated mechanical and electronic calculators.
