## Journal daniil's Journal: How history of Mathematics was made 5

Here's an interesting article from American Scientist Online about the famous story of Carl Friedrich Gauss and the schoolmaster who gave his class the tedious assignment of summing the first 100 integers. The author thinks that "only one kind of student would ever be likely to add the numbers from 1 through 100 by performing 99 successive additions -- namely, a student using a computer or a programmable calculator", yet still finds that other, quite apparent shortcuts "can't match the elegance and ingenuity of Gauss's method."

Anyone who bothered to add up all the numbers would quickly run out of fingers ...Yes, that's exactly the point the author of the article is trying to make. We don't know how the other kids (or the teacher) solved the problem (probably by using a less elegant heuristic). We don't even know if this ever happened at all. The only thing here we know for sure is that Gauss was a bloody brilliant guy.

See, there's the difference. I learned early that if you can count on your fingers, you can also use them as placeholders while you find easier ways to work through a problem, etc.

For example, anything x 11
