When working in Microsoft Excel, it is very likely that you will sometimes need to open more than one workbook at a time. Excel allows you to do this and to navigate between the open workbooks in a number of ways.
To open several workbooks, click on the Office button and choose "Open. You can only open several workbooks at once if they are in the same folder. To highlight a range of workbooks, click on the first, hold down the Shift key on the keyboard and click on the last.
To select individual files in an arbitrary fashion, click on the first file, hold down the Control key, click on the second, third, and so forth. You can also drag a selection rectangle around a series of files to highlight them. When you do so, make sure you start in blank space rather than starting on an item. Having highlighted the files that you want to open, click on the Open button.
Excel opens each of the selected files in a fully maximised window. This means that you can only see one workbook at a time. To switch between documents you can use the Windows taskbar and choose a particular name. You can also click on the View tab of the Excel Ribbon where you will find the Switch Windows button. This lists all the windows you currently have open. You can simply choose the name of a workbook to activate it.
The Window section of the View tab also contains an option for tiling your Windows. Just click on the Arrange All button and choose Tiled. When you click OK, Excel arranges all the open files into separate small windows so that you can see the contents of all files simultaneously. To activate any document, simply click on any part of its window.
To exit tiled mode, click on the maximise button of any of the open files. This action maximises all the open windows so when you switch windows, you will find that all of them have been maximised.
Regardless of which window display mode is currently active, you can use the keyboard to switch between the various files that you have open in Excel at any given time. To do this, hold down Control and press the Tab key on your keyboard.
A particularly useful feature of Excel is the ability to switch windows when you are in the middle of creating a formula. This makes it easy to create formulas with external references. For example, if you are creating a formula containing the VLOOKUP function but the lookup table resides in a separate workbook, just make sure that both workbooks are open before you begin creating the formula. At the point where you need to specify the location of the lookup table, use any of the techniques discussed above to switch workbooks and drag across the cells containing the lookup table.

As most of us know, to create an Excel formula, you start by typing an equal sign: this distinguishes it from other types of data. A formula is made up of a series of expressions. There are three main components in these expressions: mathematical operations, such as addition and subtraction; functions; and cell references.
To create a formula which calculates the total of two of the numbers in a spreadsheet (say 3 and 34), we could simply type "=3 34". When we press the Enter key, we would see the correct result. However, the formula would have no link to the two cells which contain the numbers. If the data in the cells were to change, the formula would still calculate the old result.
Obviously, the solution is to ensure that our formula contains a reference to the two cells in question. The simplest way of doing this is to click on the first cell having typed "=". Excel then automatically creates a reference to that cell. Next type the plus sign and click on the second cell. Excel creates a reference to the second cell and we then confirm the formula either by clicking on the Enter button (on the left of the formula bar) or pressing the Enter key on the keyboard.
Now that our formula contains a reference to these two cells, any time the cell contents change, the result returned by formula will be updated.
If this was the only way of performing calculations in Excel, formulas would very quickly become extremely long and very complex. To avoid this, we can use Excel's built-in functions. Functions perform complex mathematical calculations without the user having to worry about how the result is arrived at.
For example, imagine that we wanted to add up the contents of a hundred different cells. If we relied purely on addition, we would end up creating a formula with a hundred different arguments; in other words, a hundred cell references to each of the cells containing the numbers. Thankfully, we can use the SUM function instead.
To use a function in a formula, type "=" followed by the name of the function. Next type open brackets and enter the arguments of the function. The arguments of the function are the values required by that function in order to return a result. In the case of the SUM function, we simply need to specify which cells contain the numbers we want to total. We can do this by clicking or dragging across the cells that contain those numbers.
When you have entered a reference to all cells containing numbers that we want to total, you can confirm entry of the formula by pressing the Enter key. You don't even need to close the brackets. Excel will close them for you.
