            Addition of More Than Two Numbers


            How addition can be done with multiple addends ?


            Let’s look at the concepts that are used with multiple addends.


                                                                         1 2

            12 + 34 + 43 = ?                    or                       3 4

                                                                  +      4 3

                                                                          ?




            When you add 2-digit and 3-digit numbers, you start with the ones column.

            The same rule applies if you are adding three values.

            Start with the ones. From the above example, you would add 2 + 4 + 3 = 9.

            This is a nice clean problem with no carrying.


            Your answer for the  ones  column  is  nine  (9). Then,  you  move  to  the  tens

            column.

            1 + 3 + 4 = 8 gives you a tens value of eight (8). Put it all together and you

            get the sum 89. Thus, 12 + 34 + 43 = 89.
