                  Make 10 and add.

                  VertiCAl Addition

                  We know that

                                                      and             make

                                        7              +        3        =                  10
                  To add 7 and 3, we can also arrange the numbers one below                         7

                  the other and add as shown on the right.

                  Vertical addition is a mathematical operation where two or                    +   3
                  more numbers are added by writing them one below the

                  other, with the digits of the same place value aligned in                         10

                  columns.
                  Example: Add 6 and 8 vertically.

                  Solution:  We write the numbers in columns and add using                    Draw the lines for two numbers.

                               lines as shown here.                                           Count all the lines together and
                                                                                              write the number as their sum.
