Maths Puzzles: Cryptarithms, Symbologies and Secret Codes

Join recreational mathematician, Dr. Yossi Elran, and learn how to solve symbology puzzles, decipher Egyptian hieroglyphics, read barcodes, break secret codes and solve cryptarithms. This course is given in English.

In this free online course, we’ll look at three types of math puzzles, explore their history, meet the puzzlists who created them, study and practice problem-solving techniques.
Each week, we’ll tackle a different type of encrypted math puzzle, including cryptarithms, symbologies, and mathematical operator puzzles.
By the end of the course, you’ll have upgraded your problem-solving skills; gained knowledge and insight into the history, art, and methodology of deciphering encrypted puzzles; and exercised your brain with many fun challenges.
