How old was Blaise Pascal when he invented the calculator?
28
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.
When was the adding machine invented?
