Named cells in MS Excel
The cell in Microsoft Excel could have special name.
It makes the work more convenient and understandable.
For example, it’s much more easy to reference the cell as "Salary", than "S25".
To create a named cell in Microsoft Excel, move the cursor to the "Name Box" and enter the new name of the cell.
After this the new name could be used everywhere in charts, formulae and cell references.
You could use the following formula "=Salary*(I1+0.2)"
instead of "=S25*(I1+0.2)".
