## What is a calculator?

A calculator is a portable electronics device that can solve problems ranging from simple mathematical problems to complex mathematics.

## Who invented the calculator?

After a long period of research aimed at solving mathematical problems and simplifying the process of adding, subtracting, multiplying all kinds. In 1642, the German astronomer Wilhelm Schickard invented the first calculator.

About a decade later, Blaise Pascal, a French mathematician and physician, made a detailed study of the calculator.

However, the first solid-state electronics calculator was invented in 1960. However, it was much bigger. Then, in 1970, Intel introduced the pocket size calculator. Intel originally invented the modern calculator by inventing the first microprocessor for the Japanese company Busicom.
