There areThree sorts of cell references. These are:
• Relative
• Absolute
• Mixed
A relative reference will change column and row numbers as it is copied to other cells. Think of it as an original instruction being to go in a certain direction e.g. 2 rows up and 2 columns across from your current position. When this instruction is copied elsewhere, it will still refer to 2 rows up and 2 columns across from your new current position.
An absolute reference is one that does not change. If you refer to a cell in a certain row and column and then copy that reference elsewhere, it will still refer to exactly the same cell or range.
A mixed reference is one that is half relative and half absolute.
An absolute address is defined with the use of the “$” symbol. This can be typed in at the time of creating the formula, or by editing the cell afterwards. Examples of relative and absolute addressing:
Relative
A4 A4:B5
Absolute
$A$4 $A$4:$B$5
Mixed
$A4 or A$4 $A4:B$5
