NUMBER GRID


              In a number grid each grid is replaced by the value of its result. Let us start filling the
              numbers in the grid by solving each grid.

                  We usually start with the number at the centre. Here, it is 30.



                                         10 less
                                         than 30



                                                     1 more
                             1 less                   than
                            than 30      10+20         30                              30




                                        10 more
                                        than 30


                  Now, fill the remaining places in the grid according to the instructions in each box.

                                          than 20


                              11 less                  11
                                than        20       more
                                 20                 than 20


                                          18 less
                                         than 20








                                  What if you could use computer to create secret codes that only your friends
                                  could decode? What would your code say, and how would you use it to
                                  communicate?
