The mechanical calculator

The mechanical calculator helped us in many ways today. The inventor, Blaise Pascal, was born in 1623. Before that there were no calculating tools and the government wasn't doing so well. His father was the Loyal tax collector, a job with a lot of responsibility, stress, and poor calculating instruments. Pascal wanted to help his father, so he created a device which could help out with math. Here is a picture of Pascal:

Commercially, the device was a failure, but he sparked interest in the invention and wrote books about it. Just think about a life without a calculator: A life where you have to do everything by hand! "Bob! Quick! What' 123,976 plus 477,000, 234?" "Well, Steve, let me get my pencil, paper, and lucky rock." That's how it would be without them. But with them, you can just turn on your phone and enter the problem in the calculator app. See what I mean? Also, we couldn't get to space without the calculator because our calculations never could have been accurate enough to launch the rocket. As a conclusion to my essay, the world would not be close to where it is now without the mechanical calculator.
