Brilliant!

Good catch - and one of the errors in the 2004 version that we caught in the review process for the 2012 edition. You'll see the new versions begin to arrive on the download page of HackerHighSchool.org soon. Give the new lesson a read when we've finished reviewing and release it. I think you'll appreciate how far we've been able to raise the quality of the curriculum, mostly because of a really terrific group of contributors. If you're this careful a reader, we'd be glad to have you join us. Glenn Norman HHS v2 Project Manager
