What if a teenager invented something that would lead to every computer and phone you use today?

The Day Blaise Pascal Built a Super Calculator!

How a teenage genius invented one of the world's first computers

A French teenager invented one of the world's first calculators to help his dad with math!

Imagine being so smart that you invented a calculator when you were just 19 years old! That's exactly what Blaise Pascal did on August 19, 1662... wait, let's go back to when he actually made it!

In 1642, young Blaise Pascal lived in France with his dad, who had a really, REALLY boring job. His father spent hours and hours adding up long columns of numbers for tax collection. Blaise watched his dad struggle with all those calculations and thought, 'There HAS to be a better way!'

So this teenage genius got to work. He designed a wooden box filled with gears, wheels, and dials. When you turned the little wheels, the machine would actually ADD and SUBTRACT numbers all by itself! He called it the 'Pascaline,' and it was one of the very first mechanical calculators ever made!

Building it wasn't easy. Blaise made over 50 different versions before he got it right! Each one had to be carefully crafted by hand. The gears had to click together perfectly, or the whole thing would give wrong answers.
