The history of calculators dates back to ancient times, with the earliest calculators dating back to ancient Babylon in 3000 BC. At that time, people used abacus and counters to perform simple calculations. With the passage of time, the technology of calculators has evolved, and various different types of calculators have emerged, such as mechanical calculators, electronic calculators, computers, etc. The mechanical calculator is one of the earliest calculators, and it works by means of a mechanical structure to achieve calculations. The earliest mechanical calculators date back to the 17th century, when mathematicians and engineers began to study how to use mechanical structures to achieve complex calculations. With the passage of time, the technology of mechanical calculators has evolved, and various different types of mechanical calculators have emerged, such as adders, subtractors, multipliers, dividers, etc. Electronic calculators appeared in the 50s and 60s of the 20th century. It works by means of electronic components to achieve calculations. The first electronic calculator was manufactured by Texas Instruments (TI) in the United States, and its appearance marked a major leap forward in calculator technology. With the passage of time, the technology of electronic calculators has evolved, and various different types of electronic calculators have emerged, such as handheld calculators, desktop calculators, scientific calculators, etc. Computers emerged in the 60s and 70s of the 20th century. It works by enabling calculations through computer programs. The first computers were manufactured by the American company IBM, and its advent marked a major leap forward in computer technology. With the passage of time, the technology of computers has evolved and various different types of computers have emerged such as personal computers, servers, supercomputers, etc. In conclusion, the history of calculators can be traced back to ancient times, and with the passage of time, the technology of calculators has evolved, and various different types of calculators have emerged, such as mechanical calculators, electronic calculators, computers, etc. The emergence and development of these calculators have greatly promoted the scientific and technological progress and social development of mankind.
