A Magic Game

  1. Think of a 'two-digit' number (e.g.78)

  2. Subtract the two digits from the number and get the 'code'.
    (e.g. the code in this case is 78-7-8=63)

  3. Find the symbol corresponds to the code in the Table below.

  4. Memorise the symbol and then press 'Ready ?'.
    (What Did you find? Can you explain it?)

  5. Hint: (10x +y) - (x+y).
