In order to create an absolute cell reference, we need to add a sign before the column letter, this can be done by pressing the key after entering your cell reference.

There are two types of cell reference, absolute and relative. Select the relative cell reference.

To change the relative cell reference A1 to an absolute cell reference you use:1 point$A$1a1A$1$"A1"ABS(A1)

Absolute referencingAbsolute referencing is marked by a dollar sign ($). For example, =$A$10 has absolute referencing for both the column and the row valueRelative references (which is what you normally do e.g. “=A10”) will change anytime the formula is copied and pasted. They are in relation to where the referenced cell is located. For example if you copied “=A10” to the cell to the right it would become “=B10”. With absolute referencing “=$A$10” copied to the cell to the right would remain “=$A$10”. But if you copied $A10 to the cell below, it would change to $A11 because the row value isn't an absolute reference.Absolute references will not change when you copy and paste the formula in a different cell. The cell being referenced is always the same.To easily switch between absolute and relative referencing in the formula bar, highlight the reference you want to change and press the F4 key; for example, if you want to change the absolute reference, $A$10, in your formula to a relative reference, A10, highli

Be sure to use absolute or relative cell referencing to refer to thevalues in the respective columns when inserting formulas
