Problem of the Week

Holiday Algebra
by Craig Wilson in Games Magazine (October 2005)



Many Christmas songs have lyrics in which a word or phrase is repeated. Several repetitive lyrics have been extracted from a number of holiday favorites.   Each algebraic expression below represents a song, where each word is represented by its first letter and exponents show the number of repetitions.   If two or more words are repeated as a group, they appear in parentheses.   For example, (JB)2 is short for "Jingle Bells, Jingle Bells."

Can you identify all the songs below?


  1. (JB)3R
  2. P(RP3)3
  3. FL8
  4. (SIHP)2
  5. N4
  6. (WWYAMC)3
  7. (OCT)2
  8. OTO(CAJ)2OTOCAJ
  9. (GIED)2
  10. (OCLUAH)2
  11. (H3WWG)2
  12. (LIS)3
  13. (FN)3
  14. (SB)2
  15. (HCSC)2
  16. (RTSJ)2 R2TSJ
  17. (OC)2E
