What I am trying to do with programs like these is to take the mystery out of numerical solutions as well as demonstrate simple Mathcad programs to my students. Many of the Mathcad progams I run in to are so convoluted and involved that it would takes days to figure out the logic. I make liberal use of comments and written explanations. I require the students to do the same. I find that requiring students to actually write code (not done much anymore) forces them to think very logically, many have a tough time at first.
