Excel SUM Function Made Easy.

The SUM function in Excel is versatile, allowing for simple addition or complex conditional summations. In this guide, we will explore various methods to use the SUM function in Microsoft Excel, making it easy for beginners and enhancing your productivity.

Step 1: Basic Addition Method

1. Manual Addition: You can manually add numbers by typing = followed by the cell references separated by +. For example:

   =A1 + A2 + A3 + A4 + A5

   This method is straightforward but not efficient for large datasets.

Step 2: Using the AutoSum Feature

1. AutoSum: Click on the AutoSum button in the Home tab. Excel will automatically suggest a range of cells to sum.

   • Example: If you select a cell below a range of numbers, clicking AutoSum will suggest that range, like =SUM(E2:E10).

Step 3: Manual SUM Function

1. Typing the SUM Function: You can also type the SUM function directly:

   =SUM(E2:E10)

   This will sum all values in the specified range.

Step 4: Conditional SUM with SUMIF

1. Using SUMIF: If you want to sum values based on a condition (e.g., values greater than 10), use:

   =SUMIF(range, criteria)

   For example:

   =SUMIF(A1:A10, ">10")

   This will sum all values in the range that are greater than 10.

Step 5: Advanced Conditional SUM with SUMIFS

1. Using SUMIFS: For multiple criteria, use the SUMIFS function:

   =SUMIFS(sum_range, criteria_range1, criteria1, criteria_range2, criteria2)

   Example:

   =SUMIFS(A1:A10, A1:A10, ">10", A1:A10, "<100")

   This sums values greater than 10 and less than 100.
