This question already has an answer here:
MathNode is a graphical language made by myself with an interpreter currently not publicized, so I'm asking this ahead of time. In MathNode, surprise surprise! You have nodes. These nodes can be connected to each other to perform calculations. Here is a screeshot showcasing some things it can do:
So basically it can do arithmetic operations, recursion (wires can connect to themselves), and node movement which is just a side effect and doesn't do anything although it can be used to show output.
It also supports input by clicking nodes, and a few other things.
So what would be the best way to score this language in code-golf challenges?
