                  subtrACtion of 2-digit numbers

                  Example 1: Ravi bought 54 eggs and out of them 23 was rotten.
                  How many eggs were good?

                  Solution: To know the number of good eggs, we                         tens Ones

                  need to subtract 23 from 54.                                            5      4

                  Step 1. Write the smaller number below the bigger                   –   2      3
                  number according to the place value of digits.

                  Step 2. First subtract the ones.

                             tens Ones

                               5      4

                           –   2      3
                                      1

                  Step 3. Subtract the tens next.

                                  tens Ones

                                    5      4

                                –   2      3

                                    3      1

                  Thus, there were 31 good eggs left with Ravi.

                  Example 2: Subtract 43 from 65.
                  Solution:

                  Step 1. Subtract the ones first.                       Step 2. Subtract the tens next.

                               tens Ones                                              tens Ones

                                 6      5                                               6      5

                             –   4      3                                           –   4      3
                                        2                                               2      2

                  Thus, 65 – 43 = 22
