Absolute References
When you
need to work with one particular cell you need an Absolute Reference.
Try it:
Create an Absolute Reference
Select
Cell D7.
The Formula bar shows
=D6+B3.
Go to the
Formula Bar and click on B3.
Click the F4 function
key on the top row of the keyboard.
What Do
You See? The cell
reference becomes $B$3. This means "go to B3 only, and no place else,"
to get the data.
Try This, Too: AutoFill the Formula
Select
Cell D7 and AutoFill the revised equation
to the rest of the rows.
A Mixed
Reference uses Absolute and Relative cell references.
