The Average of 60 and 100 is Not Always 80: The Harmonic Mean in First-Year Algebra.
Silver, Edward A.
School Science and Mathematics, v82 n8 p682-86 Dec 1982
The harmonic mean is defined, and examples of problems viewed suitable for classroom exploration are presented. Such exercises provide many opportunities for students to engage in interesting nontrivial problem-solving activities and practice on many algebraic skills. Class discussion of the arithmetic, geometric, and harmonic means is suggested. (MP)
