              checking suBtrAction using Addition

              We have learnt checking subtraction by using addition for 2-digit numbers. We do

              the same for 3-digit numbers.
              example:


                                                  Check:

                          H    t    O                 H    t    O
                               2    15                     1
                          4    3    5                 2    2    8

                      –   2    0    7             +   2    0    7
                          2    2    8                 4    3    5          Thus, the answer is correct.
