Can SUM function be used with ranges?

Absolutely! The SUM function in Excel is designed to work efficiently with ranges of cells. In fact, it's one of the most common ways to use SUM.

Here's how it works:

* Syntax: `=SUM(range1, range2, ...)`

* Arguments:

* `range1`: This is the first range of cells you want to sum the values from. You can specify the range directly (e.g., A1:A10) or select the cells with your mouse.

* `range2, range3, ...`: You can add additional ranges of cells separated by commas to sum their values together in the same formula.

Examples:

* `=SUM(A1:A10)`: This formula sums the values in cells A1 through A10.

* `=SUM(B2:B5, C2:C5)`: This formula sums the values in cells B2:B5 and C2:C5, effectively adding corresponding cells across the two ranges.

Benefits of using ranges:

* Saves time: Instead of manually adding each cell value, you can sum an entire range with one formula.

* Reduces errors: There's less chance of introducing typos by referencing a range instead of individual cells.

* Flexibility: You can easily adjust the range size by dragging the selection or modifying the cell references in the formula.

So, the next time you need to add up a group of cells, remember that the SUM function with ranges is your friend!
