                  Adding 2-digit numbers

                  Example 1: In the store room, there
                  are 36 boxes of corn flakes and 22

                  boxes of cheerios. How many boxes of

                  Solution: To know the total number of

                  cereal boxes, we need to add 36 and

                  22.
                  Step 1.  First arrange the  Step 2. Add the ones first. Step 3.  Now, add the

                            numbers one below          6 ones + 2 ones = 8 ones                     tens.
                            the other keeping          Write 8 in the ones                3 tens + 2 tens = 5 tens

                            in mind the place          column.                            Write 5 in the  tens
                            value of the digits.                                          column.

                               tens Ones                            tens Ones                          tens Ones

                                 3     6                              3      6                           3     6
                            +    2     2                          +   2      2                      +    2     2
