there must be tons of functions that are easy to process one way but almost impossible the other.

i get the feeling there is more to it than finding such a function, but the article doesnt get into that

Seeing the below error when visiting the site.

I'm really not into math and got really lost in the second half of "Adding points on a curve". Just don't understand what the author wants to tell me with the grouping and the role of the identity element, which is called infinity but is zero?

However, after looking at the next section and playing with the chart I immediately got the idea where the whole article is heading. Interesting to see how this works.
