    I don't know what 33 is, but it looks like your #5 equals 20.

    They have entire portions of websites dedicated to this. Most of them are common sense - for my class years ago, we had the option of doing this for extra credit and I found almost all of them by myself (and somewhat enjoyed it). If you really get stuck, though, I recommend Wikipedia (http://en.wikipedia.org/wiki/Four_fours) and just searching Google, which almost always yields results (i.e. http://www.dwheeler.com/fourfours/fourfours.txt).

    If you don't want just answers - for #33, remember that you can also use decimals in your equations.

    I'd double check your current answers, too.
