Answer 2

Answer:

Blaise Pascal

Explanation:

Two decades after Schickard's supposedly failed attempt, in 1642, Blaise Pascal decisively solved these particular problems with his invention of the mechanical calculator.[3] Co-opted into his father's labour as tax collector in Rouen, Pascal designed the calculator to help in the large amount of tedious arithmetic required;[4] it was called Pascal's Calculator or Pascaline.[5]
