                  VerticaL Subtraction

                  Numbers can be subtracted by writing one below the other. Such method of
                  subtraction is called vertical subtraction.

                  In vertical subtraction, we write the bigger number above and the smaller one below.

                  Example: Subtract 4 from 9.

                  Solution:  Since 9 > 4, so we write the numbers as                  Draw the lines equal to the bigger
                               shown below.                                            number. Cross the lines equal to
                                                                                        the smaller number. Count the
                                   9                                                   number of lines uncrossed which
                                                                                             gives the answer.
                               –   4
                                   5

                               Thus, 9 – 4 = 5.

                  1.  Cross (7) out to subtract. One has been done for you.

                       (a)      5                       (b)      7                       (c)      8
                            –   3                            –   5                            –   4
                                2
                       (d)      9                      (e)       6                        (f)     5

                            –   2                            –   6                            –   4

                  2.  Subtract the following by drawing lines. One has been done for you.
                       (a)      4                       (b)      8                       (c)      3

                            –   3                            –   7                            –   1
                                1
                       (d)      7                       (e)      6                        (f)     9

                            –   7                            –   4                            –   3

                  3.   Write the numbers in column form in such a way that bigger number is above
                       and smaller number is below. Then subtract.

                       (a) 3 – 2               (b) 4 – 2                 (c) 5 – 1               (d) 8 – 7

                            –                       –                        –                        –
