Pascaline, also called Arithmetic Machine, the first calculator or adding machine to be produced in any quantity and actually used. The Pascaline was designed and built by the French mathematician-philosopher Blaise Pascal between 1642 and 1644.
Who invented Pascaline machine?

Where is Pascaline invented?
The original compact calculator was the abacus, developed in China in the ninth century. The young French mathematician Blaise Pascal (1623-1662) invented the first adding machine in 1642, a clever device driven by gears and capable of performing mechanical addition and subtraction.
Who modified Pascaline?
Gottfried Leibniz invented his Leibniz wheels after 1671, after trying to add an automatic multiplication feature to the Pascaline. In 1820, Thomas de Colmar designed his arithmometer, the first mechanical calculator strong enough and reliable enough to be used daily in an office environment.
Why was Pascaline invented?
Blaise Pascal invented the machine to help his father complete tax computations more efficiently. Pascal was only 18 when he invented the calculator.
How is Pascaline different from present day?
The present day calculator has buttons compared to the Pascaline which had eight movable dials. The present day calculator can perform many complex calculations but the Pascaline could only add and subtract.
What are the features of Pascaline?
Characteristics of the pascaline
- It could only do addition and subtraction, with numbers entered by manipulating its dials.
- The Pascaline is the size of a shoebox and that’s why it can be easily carried.
- It has eight different windows at the top.
What are the advantages of Leibniz over the Pascaline?
The main advantage is that it can perform carry operation with ease and also cascading operation.
