                                 Step 3:  Subtract the hundreds.

                                          1 hundred – 1 hundred = 0 hundreds.
                                 Step 4:  Subtract the thousands.

                                           9 thousands – 5 thousands = 4 thousands

                                           Thus, 9258 – 5189 = 4069.                                     th H      t    O
                  Example 3: Find the difference of 3952 and 2189.                                                 14
                                                                                                               8   4   12
                  Solution:   Write the smaller number below the bigger in columns                        3    9   5    2
                                 and subtract starting from ones place. Regroup whenever               – 2     1   8    9

                                 required.                                                                1    7   6    3
                                 Thus, the difference of 3952 and 2189 = 1763.

                  Example 4: Subtract 398 from 3264.                                                     th H      t    O

                  Solution:   Write the numbers in correct columns and subtract using                         11   15
                                 the following steps:                                                     2    1   5   14

                                 Step 1:  Since 4 < 8, so, regroup the tens into ones to                  3    2   6    4
                                          subtract ones.                                               –       3   9    8

                                           14 ones – 8 ones = 6 ones                                      2    8   6    6

                                 Step 2:  Again, 5 < 9 so, regroup the
                                          hundreds into tens to subtract                Get it right!
                                          the tens.                                Subtract 349 from 7628.

                                           15 tens – 9 tens = 6 tens                  th H t O           th H t O

                                 Step 3:  Again, 1 < 3, so regroup the                7 6 2 8             7 6 2 8
                                          thousands into hundreds to                –     3 4 9        – 3 4 9
                                          subtract the hundreds.

                                            11 hundreds – 3 hundreds = 8 hundreds.

                                 Step 4:  Subtract the thousands.

                                            Since, there is no thousands digit in the subtrahend, so we assume
                                          it as '0'.
                                           2 thousands – 0 thousands = 2 thousands

                                           Thus, 3264 – 398 = 2866.
