[Haskell-cafe] I have a question about Haskell

Several people have posted about this homework problem on StackOverflow
today, including one person whose name and code look very much like yours:
http://stackoverflow.com/questions/36778193/to-evaluate-polynomial-in-haskell

If that is indeed your question, I suggest you improve it by adding the
missing code. In any case, sending screen captures of your code to
haskell-cafe is not the best way to get help. Use plain text only, and send
your question to haskell-beginners instead.
