Thanks for the article and discussion that sprang up around it!

The question I'm trying to ask is how I should express (part of) programs on paper using math when I don't see how they are related to math.

Example: How could I easily express a function that takes a string as input and outputs the string capitalized using math notation?

I understand that the problem you solve in the post should probably be put on paper first before you began writing any code.

My problem is to express programs in math when "calculate" isn't part of the problem description, like it is in the example in the blog post.

Edit: Changed example question.
