                  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.

                  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
