                To solve problems that involve both addition and subtraction, we first perform addition
                and then perform subtraction.

                Example 1. Solve: 2345 + 5361 – 3694.

                Solution.        Th  H T O                        Th  H T O                            Tips
                                 2   3 4 5                        7   7 0 6
                              + 5    3 6 1                     – 3    6 9 4               We  first  find  the  sum  of
                                                                                        2345 and 5361 and then find
                                 7   7 0 6                        4   0 1 2             the  difference  of the  sum

                                                                                        obtained and 3694.
                Therefore, 2345 + 5361 – 3694 = 4012.
