                  example 3: Find the sum of 7428 and 2387.

                  Solution:   Arrange the numbers in the place value column and add using the following
                                 steps:
                                 Step 1: Add the ones.

                                           8 + 7 = 15 ones = 1 ten + 5 ones

                                           Write 5 in the ones column and carry over 1 ten in the tens column.
                                 Step 2: Add the tens.                                                   th H      t   O

                                           1 (carried over) + 2 + 8 = 11 tens                                  1   1

                                                                      = 1 hundred + 1 ten                 7    4   2    8
                                            Write 1 ten in the tens column and carry over 1            + 2     3   8    7

                                          hundred in the hundreds column.                                 9    8   1    5
                                 Step 3: Add the hundreds.

                                           1 (carried over) + 4 + 3 = 8 hundreds
                                           Write 8 in the hundreds column.

                                 Step 4: Add the thousands.

                                           7 + 2 = 9 thousands
                                           Write 9 in the thousands column.

                                          Thus, the sum of 7428 and 2387 is 9815.

                           Think and Answer
                        There are seven number cards given here. Put these cards in the two baskets
                        in a way so that the total value of the cards in both the baskets are same.          2000
                                                                                                       1000         1200
                              1: _______________                  2: __________________                      1500

                                                                                                          800     500

                  example 4: Find the sum of 6052, 2456 and 1201.

                  Solution:  Arrange the numbers in the place value columns and follow the given steps:
                                 Step 1: Add the ones.  2 + 6 + 1 = 9 ones.                              th H      t   O

                                 Step 2: Add the tens.   5 + 5 + 0 = 10 tens                                   1

                                                                           = 1 hundred + 0 tens           6    0   5    2
                                 Step 3: Add the hundreds.                                                2    4   5    6

                                           1 (carried over) + 0 + 4 + 2 = 7 hundreds                   + 1     2   0    1
                                                                                                               7
                                                                                                                   0
                                                                                                                        9
                                                                                                          9
                                 Step 4: Add the thousands. 6 + 2 + 1 = 9 thousands
                                              Thus, 6052 + 2456 + 1201 = 9709
