Answer 2

Explanation:

Pascal's calculator (also known as the arithmetic machine or Pascaline) is a mechanical calculator invented by Blaise Pascal in the mid 17th century. Pascal was led to develop a calculator by the laborious arithmetical calculations required by his father's work as the supervisor of taxes in Rouen.[2] He designed the machine to add and subtract two numbers directly and to perform multiplication and division through repeated addition or subtraction.
