Answer :
To calculate data across worksheets in Excel, you can use the following procedure:
1. Open your Excel workbook containing the worksheets you want to work with.
2. Click on the worksheet where you want the final calculation to be displayed.
3. In the cell where you want the result to appear, start typing the formula as you would for a regular calculation.
4. When you need to refer to data from another worksheet, click on that worksheet tab at the bottom of the Excel window.
5. Select the cell or range of cells you want to include in your calculation. Excel will automatically insert the sheet name followed by an exclamation mark before the cell reference, indicating that it's pulling data from a different sheet.
6. Complete your formula as needed, including data from different worksheets.
7. Press Enter to calculate the result that references data across worksheets.
Relative Cell Reference in Excel means that when you copy a formula to another cell, the cell references within the formula adjust automatically based on their relative position to the new location. For example, if you have a formula "=A1+B1" in cell C1, and you copy this formula to cell C2, Excel will adjust it to "=A2+B2" because the references are relative to the new cell. This makes it easier to replicate formulas across multiple cells without manually changing the references.
Understanding how to work with data across worksheets and utilizing relative cell references can help you streamline your Excel calculations and analysis efficiently.
