              Step 1.   Since, there are not enough  Step 2.  Then subtract the ones.

                         ones, so borrow 1 ten from 3                         14 – 8 = 6 ones

                         tens and regroup 10 ones with                        Write 6 in ones column.

                         4 ones.
                                                                                  t   O
                             t    O                                               2   14

                             2    14                                              3    4
                             3    4                                           –        8
                         –        8                                                    6




              Step 3.   Subtract the tens.                         david: Okay, I understand. Now I try to

                         2 – 0 = 2 tens                            subtract 6 from 20.

                         Write 2 in tens column.                   First regroup 1 ten = 10 ones.

                              t   O                                Then, subtract 10 – 6 = 4 ones

                              2   14                               and 1 – 0 = 1 ten
                              3    4                                                t    O
                          –        8                                                1    10
                              2    6                                                2    0

                                                                                –        6
                                                                                    1    4
              Hence, 34 – 8 = 26

                                                                   Hence, 20 – 6 = 14

              Subtraction of two 2-digit Numbers

              Let us understand it through examples.

              example 1: Subtract 36 from 52.

              Solution:  Write the numbers in columns according to the place value of digits
                              and subtract step-wise.


              Step 1.   Subtract the ones.                                                                    t   O
                         Since, 2 < 6, so borrow 1 ten from 5 tens.                                           4   12

                         1 ten + 2 ones = 10 ones + 2 ones = 12 ones                                          5    2

                         Now, 12 – 6 = 6 ones                                                             –   3    6

                         Write 6 in the ones column.                                                               6
