                      SECRET MESSAGE: DECODING

                  Decoding is the process of converting a hidden message to a meaningful text.
                  The hidden message or secret message can be in the form of a symbol, number,
                  picture, letter, or a pattern.

                  For example, if                 1              2            3  then the secret message


                                         will be decoded as 132112.

                     Recap

                          In a number pyramid, the number in each space is the sum of the two
                         numbers below it.
                          In a number grid each grid is replaced by the value of its result.

                         text.
