                  3.  Find the sum of the following. One has been done for you.
                        (a)      T    O          (b)      T    O         (c)       T    O         (d)       T    O

                  ADDING THREE 2-DIGIT NUMBERS

                  David, Harsh and Vicky

                  participated in an interschool

                  cricket tournament.

                  David, the captain, scored 25
                  runs, Vicky scored 22 runs

                  while Harsh scored 12 runs

                  in the match. What was their

                  total score?

                  David calculates the runs they scored in the match as follows.                                  T    O
                                                                                                                  2    5
                  Step 1.  He writes the numbers in tens and ones columns, one below                              2    2

                             the other.                                                                       +   1    2

                  Step 2.   Then, he adds the ones first.              Step 3.  Next, he adds the tens.

                           T    O                                              T    O
                           2    5                                              2    5

                           2    2                                              2    2
                       +   1    2                                          +   1    2

                                9                                              5    9

                   Thus, they scored 59 runs.

                  Let us look at some more examples.
                        (a)      T    O          (b)      T    O         (c)       T    O         (d)       T    O

                                 1    3                   2    1                   4    1                   1    0
                             +   2    1               +   3    2               +   1    6               +   5    3
