Yes you can. That is part of the reason for having them. It makes referring to cells or ranges easier and makes formulas easier to understand like in the two sets of examples below:
=SUM(A2:A20)
=SUM(Income)
=B20-A20
=Income-Expenses
Yes you can. A name can be applied to a single cell or to a range of cells. Naming a cell can be handier than trying to find or remember the address of a cell. That could give you a formula like: =Total_Sales * Tax_Rate This is obviously easier to understand and although it takes more keystrokes to type than an address would, the user does not have to remember the cell addresses used.

There is no single formula. MIN(range) and MAX(range) are the Excel formulae
There are several functions of Excel that do not work with 3D formulas. These include cell references and range formula.
If your data range is a1:a10 then the interquantile range equation is =percentile(a1:a10,0.75)-percentile(a1:a10,0.25)
It allows you to quickly fill a range of cells with some data or a formula.
Range finder. Double clicking on the formula activates the range finder and you can see what cells are in the formula. This can help you see if the correct cells are in the formula.
=SUM(X1:X10)
It can simply be a range. It could also be an array. It will depend on the formula itself.
The Range Finder feature is enabled when a user creates a new formula or edits an existing formula. The Range Finder gives users better visual feedback for moving and resizing the Range Finder range. You can see the ranges included in the formula are highlighted by different color border lines.

The first key you type in Excel to create any kind of formula is the equal sign (=). If you are trying to create an array formula press CTRL+SHIFT+ENTER. Excel surrounds the formula with braces ({ }) and places an instance of the formula in each cell of the selected range.
