One of the most commonly used function in spreadsheets is the SUM function that you are are reading about this week.  Describe a scenario where you could personally use the SUM function in a worksheet and briefly discuss what factors you would consider in deciding to take the time to set up SUM functions in a spreadsheet vs. just manually updating totals with a calculator.

Additionally, submit an Excel or Google Sheets attachment that contains a column of at least 3 values and with a Total row at the bottom that uses the SUM function to add those cells.  To better showcase your data, look to label your values in a column to the left and label your Total row as well.  Feel free to get creative with formatting, the kind of numerical values you are adding, and your subject matter. (Remember: do not include any personal data for you or friends/family in these submissions)
