              example:   The population of a town is 83,426. If there                               12   13   11

              are  48,967  males,  how many females are  there  in the                        7     2     3   1    16
              town?                                                                          8      3    4    2    6

              Solution:  Total population of the town  = 83,426                         –    4      8    9    6    7
                            Number of males                      = 48,967                    3      4    4    5    9

                            Number of females                    = 83,426 – 48,967 = 34,459
                            Thus, there are 34,459 females in the town.

              addition and subtraCtion together

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

              example 1: Solve: 32,345 + 25,361 – 23,694.

              Solution:   We first find the sum of 32,345 and 25,361 and then find the difference
                            between the sum obtained and 23,694 as shown below.

                               tth th H t O                         tth th H t O

                                          1                                    6   10
                                3     2   3 4 5                       5    7   7 0 6
                            +   2     5   3 6 1                  –    2    3   6 9 4
                                5     7   7 0 6                       3    4   0 1 2

                             Thus, 32,345 + 25,361 – 23,694 = 34,012.
