If you're experiencing this issue, it could be due to a number of different factors. Let's take a look at each one:

1. Cell Formatting

The first thing to check is the formatting of the cells in question. If the cells are formatted as text, they may not display the correct numerical value. To fix this, simply select the cells and change the format to General or Number.

2. Data Type

Another potential issue could be the data type of the cells in question. If the data type is set to Date or Time, Excel will automatically format the cell accordingly. To fix this, simply select the cells and change the data type to General or Number.

3. Cell Reference

If you're referencing another cell in the formula for a particular cell, make sure that cell is displaying the correct value. If it's not, the formula will return an incorrect result.

4. Circular References

A circular reference occurs when a formula refers back to itself. This can happen if you accidentally create a self-referencing formula or if you're using iterative calculation. Either way, it can cause your formulas to return incorrect results. To fix this, simply remove any self-referencing formulas or disable iterative calculation.

5. Incorrect Formula Syntax

If you're getting an error when trying to enter a formula, it's likely due to incorrect syntax. This is easy to fix - simply check your syntax against the correct syntax for the particular function you're using and make any necessary corrections.
