                            Step 3:     Add the hundreds. 4 hundreds + 3 hundreds = 7 hundreds

                                        Write 7 in the hundreds column.
                            Step 4:     Add the thousands. 2 thousands + 4 thousands = 6 thousands


                                        Write 6 in the thousands column.
                            Step 5:    Add the ten thousands. 3 ten thousands + 2 ten thousands = 5

                                        ten thousands. Write 5 in the ten thousands column.

                            Thus, 32,475 + 24,312 = 56,787

              example 2: Add 4,71,223 and 2,21,252.
              Solution:  Step 1:  Add the ones. 3 ones + 2 ones = 5 ones                   L tth th H          t   O

                                       Write 5 in the ones column.                         4     7    1   2    2    3

                            Step 2:  Add the tens. 2 tens + 5 tens = 7 tens             + 2      2    1   2    5    2
                                       Write 7 in the tens column.                         6     9    2   4    7    5

                            Step 3:  Add the hundreds. 2 hundreds + 2 hundreds = 4 hundreds
                                       Write 4 in the hundreds column.

                            Step 4:  Add the thousands. 1 thousand + 1 thousand = 2 thousands

                                       Write 2 in the thousands column.
                            Step 5:   Add the ten thousands. 7 ten thousands + 2 ten thousands = 9
                                       ten thousands.

                                       Write 9 in the ten thousands column.                           Note

                            Step 6:  Add the lakhs. 4 lakhs + 2 lakhs = 6 lakhs              In an addition, the first
                                                                                             number is also called
                                       Write 6 in the lakhs column.                          augend. For example in

                            Thus, 4,71,223 + 2,21,252 = 6,92,475                             10 + 11 = 21, 10 is the

              example 3: Add 52,301 + 12,257 + 20,220.                                       addend. Generally, both
