                                                             Shizuka: You are great Doraemon!

                                                             example:  Add 473 and 359.
                                                             Solution:  Arrange the numbers in columns and

                                                             add step-wise starting from the ones place.

                                                             Step 1.  First add the ones and                 H    t    O

                                                                       regroup.                              1    1

                                                             Step 2.  Next add the tens and                  4    7    3

                                                                       regroup.                          +   3    5    9
                                                                                                             8    3    2
                                                             Step 3. Now, add the hundreds.
                                                                       Thus, 473 + 359 = 832
