300 - 300 = 0
60 - 30 = 30
8 - 5 = 3
100 + 0 + 3 = 103 4. 463 - 321 = 142
                                                                                     400 - 300 = 100
                                                                                        60 - 20 = 40
                                                                                           3 - 1 = 2
                                                                                   100 + 40 + 2 = 142





2. 435 - 224 = 211
400 - 200 = 200
30 - 20 = 10

                                                                            40 - 40 = 0
                                                                              9 - 5 = 4
                                                                         300 + 0 + 4 = 304






3. 675 - 343 = 332
600 - 300 = 300
70 - 40 = 30
5 - 3 = 2

                                                                                      400 - 300 = 100
                                                                                       40 - 40 = 0
                                                                                         3 - 1 = 2
