Absolute references
can you explain why we must use absolute formulas in some instances?
RE: absolute references
Hi Jo
Thank you for your question.
The concept of an absolute reference can be confusing, but it is useful to know how to change a cell into an absolute reference if you need to.
The idea behind this is that if you put together a formula, for example, =A1*B1 (multiples what is in cell A1 by what is in cell B1) the cells in the formula will change when it is copied to another cell in the spreadsheet.
If you need to make Excel keep multiplying by the value in cell B1 when you copied the formula to another cell in the spreadsheet, then you would need to make cell B1 an absolute reference so the formula would look like this =A1*$B$1
This means that if the formula is copied to another cell in the spreadsheet, cell B1 will remain constant or fixed in the formula - it will not change when the formula is copied to another cell.
I hope this helps.
