How to Add Two Cells Containing the Sum of Other Formulas in Excel

This How.com.vn teaches you how to use the SUM function to add two cells containing other SUM formulas in Microsoft Excel. If you get an error when trying to add your two cells, it's usually because one of your original formulas contains additional characters or multiple functions. You can fix this by placing such formulas inside the =VALUE() function.^{[1]XTrustworthy SourceMicrosoft SupportTechnical support and product information from Microsoft.Go to source}

To do this, double-click the Excel document that contains your data in Finder (Macs) or File Explorer (Windows). Alternatively, if you already have Excel open, click File > Open and select the file that has the data you want to add.

Add =VALUE around the formulas in the cells you're adding together. If the cells you're adding together use formulas that contain non-numeric characters, then you'll need to add =VALUE at the start of those formulas in order to use the SUM function.^{[2]XTrustworthy SourceMicrosoft SupportTechnical support and product information from Microsoft.Go to source}
- If either of the cells you're adding contains anything other than the standard =SUM() formula, you'll have to enclose that whole formula within the parentheses of the =VALUE() function to avoid errors. Do the following in each of the cell you're adding:
- Double-click the cell containing the formula.
- If the formula is standard, such as =SUM(A1:A15), you don't have to make any changes.^{[3]XTrustworthy SourceMicrosoft SupportTechnical support and product information from Microsoft.Go to source}
- If the cell contains other functions (such as IF or AVERAGE), letters, or quotes, enclose the formula within the parentheses of the =VALUE() function.
- For example, =SUM(AVERAGE(A1:A15),AVERAGE(B1:B15)) would become =VALUE(SUM(AVERAGE(A1:A15),AVERAGE(B1:B15) )).

This is where you'll enter the formula that adds the other two cells together.
Type =SUM() into your selected cell.

Enter the names of the cells that contain the sums you want to add. You'll enter these two cell names (e.g., A4 and B4) inside the parentheses, separated by a comma.^{[4]XTrustworthy SourceMicrosoft SupportTechnical support and product information from Microsoft.Go to source}
- For example, if you're adding the values of cells A4 and B4, your formula should look like this:=SUM(A4,B4)
- If you're adding a range of cells, like an entire column, enter =SUM(A4:24). You can also add multiple rows or columns to your equation, like =SUM(A4:24, C2:C10)^{[5]XTrustworthy SourceMicrosoft SupportTechnical support and product information from Microsoft.Go to source}
6
Press ↵ Enter or ⏎ Return. This adds the values of the two cells and displays the sum.
- If the value of either of the two added cells changes, the result of your new formula will also.
- You can update all formulas on the sheet by pressing F9.

How do you add a column of numbers (numbers derived by multiplying 2 cells) ex: cells A1 x A2, A1 x A3... all the way to A1 x A37. The total would show on A38.
