Addition can be done using fingers. For example, let’s add 4 and 3.

                •  Count  the  first  number  on  your  fingers.  So,  count  4

                   fingers and fold the remaining fingers.

                •  Now, count the second number on the remaining fingers.
                   So, count 3 more fingers.

                •  The total number of fingers is the answer.

                   So, 4 + 3 = 7.


              2   Check the addition. Then put a tick () or a cross ().
