excel

There are different 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$5
The “$” sign can be hand typed or inserted by pressing the keyboard shortcut F4.  As you press F4 the cell address will cycle between the four variations of an address – for example A4 would cycle between:
   A4    $A4    A$4    $A$4
