# Difference between Pascaline calculator and Leibniz calculator

**1. LEIBNIZ CALCULATOR :**

The Leibniz calculator is also called as Leibniz wheel or stepped drum. It is a type of cylinder which is there in the form of a set of teeth of incremental lengths that can be added to the counting wheel. It can be used in the calculating engine of a class of mechanical calculators.

In the Leibniz calculator, there are many functions like addition, subtraction, multiplication, and division are performed. it was more fast and time-consuming. It can do the calculations easily.

**2. PASCAL’S CALCULATOR :**

It is a mechanical calculator that normally represents the position of each digit with the help of gears in it. The main purpose of this is to Adding and subtracting two numbers directly and also performing multiplication and division through repeated addition or subtraction. It is made up of metal The calculation of numbers is being done by turning the wheels clockwise.

**Difference between Pascaline calculator and Leibniz calculator :**

PASCAL’S CALCULATOR | LEIBNIZ CALCULATOR |
---|---|

It can only do addition and subtraction. | It is also called a Leibniz drum. |

The Pascaline size is the same as the shoebox and because of this drumsit can be carried easily. | In this, there are many functions like addition, subtraction, multiplication, and division are being performed. |

Pascal calculator has eight different windows on the top of it. | It can do calculations very easily. |

Inside the pascal calculator the small drum is seen with the digits of the result. | It can be used in the calculating engine of a class of mechanical calculators. |

In the pascal calculator, Each of its drum is made up of two different number of rows. | It is the type of calculating machine which is called as Step Reckoner. |

There are 8 adjustment mechanisms in the front of each window. | Leibniz was a strong advocate of the binary system. |

The wheels will move according to the positions as they correspond to the value of the corresponding digit. | Leibniz calculator is also known as the first true four-function calculator. |

It uses a wheel for calculation. | It works faster and in a speedier way. |

It is slower in speed. | It is faster in speed. |

The calculations are being done by turning the wheels clockwise. | It is time-consuming. |
