Addition of 2-Digit Numbers with 2-Digit Numbers


            Without Regrouping


            Adding two digit numbers is same as adding one digit numbers.

            Let us know how.

            Example : Add : 16  + 12                                                       First, add

                                                                                 the ones, i.e., 6 + 2 = 8
                                                              T O
                                                              1 6

                                                        + 1 2
                      Then, add the

                  tens, i.e.,  1 + 1 = 2                      2 8








                  T O

                  1 6
                                             The correct sum
            + 1 2
                                                 will be 28.
                  2 8



            Now, look at the following.


            Step 1 :  First, add the ones.


                          6 ones + 2 ones  = 8 ones



                          Write 8 in the ones place.


            Step 2 :  Then, add the tens.


                          1 ten + 1 ten = 2 tens


                          Write 2 in the tens place.


                          Therefore, 16 + 12 = 28.
