The SUM function automatically adds the values in a range of cells to provide a total, saving time compared to manually adding cells and reducing errors. To use it, select the cell where you want the total and type =SUM followed by the cell range in parentheses, such as =SUM(A2:A9) to total the values from cells A2 through A9. Using the SUM function provides accurate totals and helps avoid billing errors or fraud.

How to Use the Sum Function

2. Why use the SUM Function?
• The values of adding cells and columns are too
numerous to state here in this presentation. The
simples reason is that you want to be able to
count automatically without having to use a
calculator and to go one by one counting up all
the cells. This is because doing so will take you a
lot of time and lead to incorrect results. Incorrect
results lead towards scams and frauds when you
charge customers incorrect amounts for items
they purchase or other similar issues.

3. How to Implement This Function
• It is very simple. Let’s say you have a list of
values from cell A2 – A9 – these all list the
number of bills that your client has yet to pay
you for. If you want the total to be calculate on
A10 (or A11) go to that cell and type in the
following: =SUM(A2:A9).
