From Abacus to iPhone: A Brief History
The concept of a calculating device is thousands of years old, starting with the abacus. However, the first mechanical calculator was invented by Blaise Pascal in the 17th century. The real revolution came in the 20th century with the advent of electronics.
The first all-electronic desktop calculators appeared in the 1960s, but they were large and expensive. It was the invention of the microprocessor in the 1970s that led to the creation of the pocket calculator, a device that changed the world of education and business forever. Today, a powerful calculator is a standard feature on every smartphone, but the classic button layout remains a timeless and efficient design.
