        Subtraction of 4-digit Numbers


        Subtraction without Regrouping
        Subtraction of 4-digit numbers is not different from the subtraction of 3-digit numbers.
        Only here we got to subtract one extra pair of digits at the thousands place. Arrange the

        numbers in columns as per their place values. Take care to write the greater number on
        the top and then subtract.


              Let’s Attempt


        Example 1:  Subtract 6342 from 8573.
        Solution:          Here, 8573 > 6342

                         Arrange the numbers in columns and then follow these steps:


                          Step 1:   Subtract the ones.                                             Th H T O
                                                                                                    8 5 7 3
                                     3 ones – 2 ones = 1 one                                     – 6 3 4 2

                                     Write 1 under ones column.                                                 1



                          Step 2:    Subtract the tens.                                            Th H T O

                                     7 tens – 4 tens = 3 tens                                       8 5 7 3
                                     Write 3 under tens column.                                  – 6 3 4 2
                                                                                                            3 1


                          Step 3:    Subtract the hundreds.
                                     5 hundreds – 3 hundreds = 2 hundreds                          Th H T O
                                                                                                    8 5 7 3
                                     Write 2 under hundreds column.                              – 6 3 4 2

                                                                                                        2 3 1

                          Step 4:    Subtract the thousands.

                                       8 thousands – 6 thousands = 2 thousands                     Th H T O
                                                                                                    8 5 7 3
                                     Write 2 under thousands column.                             – 6 3 4 2
                                     Thus, 8573 – 6342 = 2231                                       2 2 3 1
