The # will always be the first character shown and it will be followed by the name of the particular error. Common ones could be:
#REF!
#VALUE!
#NUM!
If you see the # repeated, it indicates that the cell is not wide enough to show the value in the cell. It is not necessarily an error.
OR
A green triangle in the upper left corner of the cell
In the formula bar.
The cell contents are what is actually typed into a cell. This is not always the same as what is displayed. So you can type a formula into a cell, which would be its contents, and the formula will do a calculation and display a result, which is the cell display. When you look at the cell you would see the result of the formula, but not the formula itself. The cell contents are always displayed on the formula bar. If you just type a number in, then the cell content and cell display can be the same. What you could then do is to format the cell and the number would be displayed in that format.
The formula will be entered and a calculation will be done and a result displayed.
That is correct.That is correct.That is correct.That is correct.That is correct.That is correct.That is correct.That is correct.That is correct.That is correct.That is correct.
If there is a formula in the active cell, then the formula will be displayed in the formula bar and the result of the formula will appear in the cell.
cell contents
The proper name is the formula bar, but yes a formula or value can be seen there when you have entered a value or formula in a cell.
In the name box, beside the formula bar.
Within the cell you may see an error which will always start with the # symbol, such as #REF! or #VALUE! You may also see a small triangle in the top right corner of the left corner of the cell, or an icon appearing beside the cell, though not in the cell next to it. If a formula has a problem as it is being typed, you may not be allowed to enter it and a message may pop up or an option showing you what can be done to fix it.
The #REF! error.
A #NAME error occurs when a function name or reference is used in a formula that cannot be found in the spreadsheet. If you were using the SUM function and accidentally type it in as SM then you would get the #NAME error, because Excel would not know what SM is.A #VALUE error occurs when you try to do a calculation on something that is not numeric. This commonly happens when you a formula to add numbers in cells refers to a cell that has text in it, meaning it can't do the calculation, as you cannot add text and numbers.
=(A1/B1)*100 then press Ctrl + Shift + % and the cell will be displayed as a percent
