&nbsp;&nbsp; Pascal foi uma das figuras mais importantes do século XVII, pois ele fez varias contribuições para os campos da ciência . Alem dessas contribuições Pascal inventou a primeira calculadora mecânica essa calculadora recebeu o nome de La Pascalina.&nbsp; A Pascalina foi construida &nbsp;entre os anos de &nbsp;1642-1644, quando Pascal tinha cerca de 20 anos
 &nbsp; &nbsp;A Pascalina Pascalina permite efectuar as operações de adição e subtracção. Embora a operação seja demorada podem efectuar-se multiplicações e divisões.
