larger numbers at top and the smaller numbers below them according to
               the place values of the digits. Start subtraction from the ones place, then

               move  tens,  hundreds  and  so  on  taking  borrow  from  the  higher  places  if
               required.


               For a subtraction fact,


                                       Minuend – Subtrahend = Difference

               There are two related facts:


                                         Minuend – Difference = Subtrahend

               and                   Subtrahend + Difference = Minuend



               Example 3:  Subtract 46853297 from 78546924.

               Solution:                         14                11

                                              7   4 14         8    1 14

                                         7 8 5 4 6 9 2 4                     →   Minuend

                                     – 4 6 8 5 3 2 9 7                       →   Subtrahend

                                         3 1 6 9 3 6 2 7                     →   Difference


                                   Check:

                                                                   1   1            1    1

                                    Subtrahend       →        4 6 8 5 3 2 9 7

                                     Difference      →    + 3 1 6 9 3 6 2 7

                                        Minuend      →        7 8 5 4 6 9 2 4


               Example 4:  Fill in the missing digit.                                         7 2 9 6 3 8

                                         7 2          6 3                                 – 2 0 5 4 2 3

                                     – 2          5        2 3                                5 2 4 2 1 5

                                              2 4 2            5

               Solution:           At O,  8  – 3 = 5;  T, 3 – 2 =  1 ; H, 6 –  4  = 2;

                                   Th,  9  – 5 = 4; T-Th, 2 –  0  = 2; L, 7 – 2 =  5
