Who was the inventor of mechanical calculator for adding numbers?
The correct option is D Pascal
Pascal was the inventor
of mechanical calculator for adding numbers.
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 supervisor of taxes in Rouen.
The First Mechanical
Calculator. Blaise Pascal, noted mathematician, thinker, and scientist, built
the first mechanical adding machine in 1642 based on a design described by Hero
of Alexandria (2AD) to add up the distance a carriage travelled.
Various forms of the
Bones appeared, some approaching the beginning of mechanical computation, but
it was not until 1642 that Blaise Pascal gave us the first mechanical
calculating machine in the sense that the term is used today.
Blaise Pascal (1623~1662)
... In 1642, at the age of 18, Pascal invented and build the first digital
calculator as a means of helping his father perform tedious tax accounting.
Pascal's father was the tax collector for the township of Rouen. The device was
called Pascal's calculator or the Pascaline or the Arithmetique.
