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.
Initially calculators were used only in the petroleum industry.
Calculators became popular in the mid-1970s due to the reduction in the size and cost of circuits. Towards the end of that decade, prices went down. Since then the use of calculators has been increasing and the use of calculators in schools has started.
