The adding machine was invented by a nineteen-year-old French boy named Blaise Pascal way back in the year 1642. Called the pascaline, it was the first mechanical calculator that used gears. He invented it to help his father calculate taxes.A different machine was invented by William Seward Burroughs in 1885.
When was 1st mechanical calculator invented?
In 1642 Blaise Pascal (a famous French mathematician) invented an adding machine based on mechanical gears in which numbers were represented by the cogs on the wheels.The abacus or counting frame was a device used for calculations that is probably 5000 years old and is still used throughout Asia and Africa.
What type of machine did 19-year-old French genius Blaise Pascal invent to help his dad do taxes in?
The year he turned 19, Blaise Pascal started work on a mechanical calculator. He finished it three years later. It was not to help his dad prepare his personal taxes, it was to help in his father's work as a tax collector. Building a mechanical calculator is pretty amazing in and of itself, but consider these two things: 1) That Blaise had not been allowed to read about or study mathematics as a child until, at age 12, he showed his dad that he had figured out some geometry on his own, and 2) That this all happened about 350 years ago.
