Who made the calculator?

Image edited and made by Sofiah Shariman, 2013

Calculators are man’s best friend when it comes down to numbers, without that very useful tool we’d be stuck on some of the hardest equations known to man. Luckily someone had the right idea when they invented this very useful tool that stands the test of time. No math class can go without the help of one of these devices for the most obvious of reasons.

so who invented the calculator???

The idea and original invention was made by a young man named Blaise Pascal, of French origin. In 1642 Blaise Pascal designed the first counting machine when he was 18. The machine was for his father, a tax collector, to make his job easier. Blaise named it the Pascaline. It was able to add two decimals together and subtract. He made about 50 of them but nobody was interested. People thought it would take jobs away. Blaise was obviously ahead of his time. 300 years went by before the calculator finally became a success. In 1968 the programming language, PASCAL, was named after him.

The idea that Pascal left behind would eventually be picked up byGottfried Leibniz. With a few improvements, he would add a number of different features to the device, putting in an addition, subtraction, multiplication, and even a divide button so there would be something here for all to use in order to solve some really hard problems. Later on another man named John Napier would invent another aspect to the calculator to be used. This new aspect was a multiplication based table that would make use of metal rods simply called “Napier’s Bones” in order to make the extra work involved in the multiplication tables better for everyone to use.
