The calculator was invented in stages: The Abacus (3000 BC) was the first calculating tool. Blaise Pascal invented the first mechanical calculator (Pascaline) in 1642. The first electronic calculator (ANITA Mark VII) came in 1961. Texas Instruments launched the first handheld calculator in 1967. Today, AI-powered calculators on smartphones have replaced all earlier versions.

The first mechanical calculator was invented by Blaise Pascal in 1642, called the Pascaline. Before that, the abacus (3000 BC) was the earliest known calculation tool.
