Subtrac on of 2-Digit Numbers

            (by Drawing Lines Without Borrowing)



            When we subtract two 2-digit numbers, first we subtract the

            digits at ones place and then the digits at tens place.


            Example :



                                                             T O

                                                             6   4


                                                          – 3   2

                                                            3   2




            Subtract the given numbers by drawing lines :



                      T O                         T O                         T O                        T O


                       4   3                      9   7                       4   5                      3   4

                   – 2   2                     – 5   6                     – 3   4                    – 2   2









                      T O                         T O                         T O                        T O

                       5   5                      7   7                       6   6                      8   8

                   – 4   3                     – 6   2                     – 5   6                    – 7   2








                      T O                         T O                         T O                        T O

                       8   9                      5   4                       7   8                      6   7

                   – 7   3                     – 4   2                     – 6   3                    – 5   4
