Detailed explanation-1: -The Pascaline Calculator is mechanical device for adding and subtracting. It can also complete multiplication and division problems through repeated addition and subtraction.
Detailed explanation-2: -The Pascaline was designed and built by the French mathematician-philosopher Blaise Pascal between 1642 and 1644. It could only do addition and subtraction, with numbers being entered by manipulating its dials.
Detailed explanation-3: -Explanation: Pascal’s calculator (also known as the arithmetic machine or Pascaline) is a mechanical calculator invented by Blaise Pascal in the early 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.
Detailed explanation-4: -Operation. The Pascaline is a direct adding machine (it has no crank), so the value of a number is added to the accumulator as it is being dialed in. By moving a display bar, the operator can see either the number stored in the calculator or the complement of its value.
