In this Class 9 Computer Applications topic from Office Tools, students learn how spreadsheet functions such as SUM simplify common calculations. They practise adding values from individual cells and ranges, entering functions with correct syntax, and using cell references in practical worksheets. The topic also helps them understand the difference between a formula and a built-in function, check results, and identify simple errors caused by incorrect ranges or entries.
