To become an Excel power user, you need to know how to use array formulas, which can perform calculations that you can't do by using non-array formulas.

If you've done even a little programming, you've probably run across the term array. For our purposes, an array is a collection of items. In Excel, those items can reside in a single row (called a one-dimensional horizontal array), a column (a one-dimensional vertical array), or multiple rows and columns (a two-dimensional array). You cannot create three-dimensional arrays or array formulas in Excel.
In order to be understood as an array formula, you have to input your formula as follows :
Highlight the range of cells that you want to input your array formula into
Type the array formula into the first cell (or if already typed into the first cell, make this cell editable by pressing F2 or clicking in the formula bar
Press CTRL-SHIFT-Enter (ie. press the CTRL and SHIFT keys, and while these are pressed down, press the Enter key
Excel will not allow you to edit just one part of a range of cells that contain an array formula, as the cells all work together as a group.
Therefore, in order to edit an Excel array formula, you need to :
Select one of the cells in the array formula
Make your alterations in the selected cell
Press CTRL-SHIFT-Enter to update the whole array
