At the age of **sixteen**, he wrote a significant treatise on the subject of projective geometry, known as Pascal’s Theorem, which states that, if a hexagon is inscribed in a circle, then the three intersection points of opposite sides lie on a single line, called the Pascal line.

## When did Blaise Pascal invented Pascal’s triangle?

In 1653, a French mathematician-philosopher named Blaise Pascal described a triangular arrangement of numbers corresponding to the probabilities involved in flipping coins, or the number of ways to choose ‘n’ objects from a group of ‘m’ indistinguishable objects. Pascal’s triangle has many uses in binomial expansions.

## How old was Blaise Pascal when he invented Pascaline?

Pascal began to work on his calculator in 1642, when he was 18 years old.

## When was Pascal invented?

Between 1642 and 1644, Pascal conceived and constructed a calculating device, the Pascaline, to help his father—who in 1639 had been appointed intendant (local administrator) at Rouen—in his tax computations.

## What did Blaise Pascal in 1640 AD?

Who Was Blaise Pascal? In the 1640s mathematician Blaise Pascal invented the Pascaline, an early calculator, and further validated Evangelista Torricelli’s theory concerning the cause of barometrical variations.

## Who first discovered Pascals triangle?

It is named for the 17th-century French mathematician Blaise Pascal, but it is far older. Chinese mathematician Jia Xian devised a triangular representation for the coefficients in the 11th century.

## Why did Pascal invent the triangle?

Pascal also made the conceptual leap to use the Triangle to help solve problems in probability theory. In fact, it was through his collaboration and correspondence with his French contemporary Pierre de Fermat and the Dutchman Christiaan Huygens on the subject that the mathematical theory of probability was born.

## What did Pascal invented?

Pascal invented the first digital calculator to help his father with his work collecting taxes. He worked on it for three years between 1642 and 1645. The device, called the Pascaline, resembled a mechanical calculator of the 1940s.

## When was the abacus invented?

The abacus is one of many counting devices invented in ancient times to help count large numbers, but it is believed that the abacus was first used by the Babylonians as early as 2,400 B.C. 1 The abacus was in use in Europe, China, and Russia, centuries before the adoption of the written Hindu-Arabic numeral system.

## When was the first mechanical calculator invented?

The first mechanical calculating machine was invented in 1642 by Blaise Pascal, a 19-year-old Frenchman. Pascal’s machine used gears and could add and subtract. Pascal’s gear system was widely used in mechanical calculators built during the next few hundred years.

## Who developed the first calculator?

The type of Abacus most commonly used today was invented in China around the 2nd century B.C. However, Abacus-like devices are first attested from ancient Mesopotamia around 2700 B.C.!

## Who was Pascal Where and when did he live?

Pascal was born in Clermont (now Clermont-Ferrand), France, on 19 June 1623, and died thirty-nine years later in Paris (19 August 1662).

## What is Pascal’s probability theory?

One of the famous problems that motivated the beginnings of modern probability theory in the 17th century, it led Blaise Pascal to the first explicit reasoning about what today is known as an expected value. The problem concerns a game of chance with two players who have equal chances of winning each round.

## Who was Pascal named after?

Death: Blaise Pascal died of a stomach tumor on 19 August, 1662 at the young age of 39. The Pascal (Pa) unit of pressure was named in his honor. The computer language Pascal is named after him in recognition of his early computing machine.
