                  Example 3. Subtract 87 - 34.                          Example 4. Subtract 97 - 26.

                  Solution.           T O                   T O         Solution.           T O                   T O

                                      8 7                   8 7                            9 7                    9 7

                                 – 3 4                  – 3 4                          – 2 6                  – 2 6

                                          3                 5 3                                 1                 7    1

                  Thus, 87 - 34 = 53.                                      Thus, 97 - 26 = 71.

                    1.  Subtract using expanded form.

                         a.       46              tens +          ones     b.       76              tens +          ones

                              -  32               tens +          ones          -  55               tens +          ones

                                                  tens +          ones                              tens +          ones

                                  46 - 32 =                                         76 - 55 =

                         c.                                                d.
                                   73             tens +          ones              88              tens +          ones

                              -    31             tens +          ones          -  44               tens +          ones

                                                  tens +          ones                              tens +          ones

                                  73 - 31 =                                         88 - 44 =

                    2.  Subtract using the short method.

                         a.        T O       b.        T O      c.        T O       d.       T O       e.        T O
