What was the first mechanical device calculator?
Ans. Abacus was the first mechanical calculating device, developed by Chinese about 5000 years ago. It was used for counting large numbers and doing arithmetic calculations such as addition, subtraction, multiplication and division.
When was the 1st calculator made?
1642
In 1642, the first true “calculator” was invented: one that performed calculations through a clockwork-type of mechanism. The Pascal calculator, invented by French inventor and mathematician Blaise Pascal, was lauded for attempting arithmetic calculations previously thought impossible.
What was the first mass produced calculator?
In 1820 The Arithmometer (or Arithmomètre) was the first mass-produced calculator invented by Charles Xavier Thomas de Colmar. It was a mechanical calculator that in addition to adding and subtracting could also perform long multiplications and divisions.
What company made the first calculator?
The first solid-state electronic calculator was created in the early 1960s. Pocket-sized devices became available in the 1970s, especially after the Intel 4004, the first microprocessor, was developed by Intel for the Japanese calculator company Busicom….Key layout.

Who invented the mechanical digital calculator?
Blaise Pascal
Invention of the mechanical calculator Blaise Pascal invented a mechanical calculator with a sophisticated carry mechanism in 1642. After three years of effort and 50 prototypes he introduced his calculator to the public. He built twenty of these machines in the following ten years.
What was the first mechanical computer called?

What is the oldest calculator?
the Abacus
Using a tool to do math and transact business has been around since 2700 BC in the Mesopatamia region. Also called a counting frame, the Abacus, is the oldest calculator in existence.

Which of the following led to the invention of the calculator?
The inspiration for Pascal’s calculator, arithmetic machine or Pascaline, was his frustration with the laborious nature of arithmetical calculations his father had to perform as the supervisor of taxes in Rouen. The key part of his machine was its carry mechanism that adds 1 to 9 on one dial.
Who invented the mechanical digital calculator called step reckoner?
Gottfried Wilhelm von Leibniz
Step Reckoner, a calculating machine designed (1671) and built (1673) by the German mathematician-philosopher Gottfried Wilhelm von Leibniz.
Why was the first mechanical computer invented in the first place?
The first mechanical computer was invented by a mathematics professor in Cambridge England named Charles Babbage. He described his new idea as a general purpose, program controlled and fully automatic mechanical digital computer. He called this the Analytical Engine.
