What did Pascaline consist of?
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.
What is the function of Pascaline?
Adding and subtracting two numbers directly and to perform multiplication and division through repeated addition or subtraction
Pascal’s calculator/Purpose
Where is the Pascaline used?
The Pascaline was designed and built by the French mathematician-philosopher Blaise Pascal between 1642 and 1644. It was used only for addition and subtraction of numbers by manipulating digits.
What are the features of Pascaline adding machine?
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.
Which is an example of a Pascaline instrument?
The first Pascaline could only use 5-digit numbers, but then Pascal developed 6-digit and 8-digit versions. Informatics history goes back to ancient times. The most remote example is the abacus, an adding instrument still used in some parts of Japan and Eastern Europe.
How did Blaise Pascal make the Pascaline calculator?
The PascalineThe Pascaline, or Arithmetic Machine, was a French monetary (nondecimal) calculator designed by Blaise Pascal about 1642. Numbers could be added by turning the wheels (located along the bottom of the machine) clockwise and subtracted by turning the wheels counterclockwise.
What was the shape of the Pascaline wheel?
Pascaline had the shape of a shoe box and was low and somewhat elongated. On the inside, there were a series of sprockets that were connected to each other, thus forming a transmission chain, so that when a wheel turned completely on its axle, it advanced one degree to the next.
What kind of gear does a Pascaline have?
Each wheel on the top of the Pascaline has an axle that has a horizontal crown gear. The gear is transmitting the wheel rotation to a vertical crown gear.
