Addition Using Expanded Form



                    To add the given numbers using the expanded form, follow these steps.

                     •  Write each number in the expanded form.


                     •  Add the values at each place.


                     •  Find the sum of the added values.


                    Let’s add 56 and 28 using the expanded form.



                                 T      O                 Expanded form                         T     O
                                 5      6                 50     +     6                       7      0


                            +    2      8             +20        +     8                  +    1      4


                                                          70     + 14                          8      4


                           So, 56 + 28 = 84.


                      5.  Add using the expanded form.


                                       T     O                 Expanded form                        T      O
                           (a)         2     5                         +



                                 +     5     6              +          +                       +

                                                                       +




                                So, 25 + 56 =             .


                                       T     O                 Expanded form                        T      O
                           (b)
                                       6     3                         +


                                 +     2     7              +          +                       +


                                                                       +



                                So, 63 + 27 =             .



                                                                                                                         45
   50   51   52   53   54   55   56   57   58   59   60
