Automatic recalculation

The default setting for calculations in Microsoft Excel is to automatically recalculate cellswhenever a change is made to the spreadsheet. For most cases, this is a convenientsetting since it allows users to see the effect of changes as soon as they are made.

However, there are other times when it makes more sense to change this setting toperform calculations manually. For instance, if you¶re working in a very largespreadsheet with several complex formulas, updating all calculations in the sheet cantake some time. In this case, it¶s pretty frustrating to have to sit and wait for the wholefile to update simply because you¶ve made one little change. Even if your file isn¶t thatbig in size, it may contain certain functions, like those that generate random numbers,that you don¶t want recalculated with every modification.

Change the Calculation

To change the method of cell calculation in Excel 2007, first go to the Formulas tab onthe Excel ribbon. Click on the Calculation Options button.

Here, you can choose one of three options.

y Automatic ± Choosing this option will cause Excel to recalculate all dependentcells whenever a change is made on the spreadsheet.

y Automatic Except for Data Tables ± As its name implies, this setting willrecalculate every dependent cell, except for the ones in data tables, each time a

change is made to the spreadsheet.

y Manual ± If you pick this option, cells will only be recalculated when you explicitlychoose to perform this action.

You can also choose to modify the default Excel settings for Calculation Options. Todo this, click on the Office button and select Excel Options.

Select Formulas. In the main window of this screen, under Calculation Options, you

have the same choices as above with one additional option. For the Manual setting, youcan also decide if you want to Recalculate workbook before saving. Again,depending on your file, you may want to uncheck this box and disable this option inorder to have complete control over formula calculations.

Excel supports many types of charts to help you display data in ways that are

meaningful to your audience. When you create a chart or change an existing chart, you

Style basics in Word

Microsoft Office Word 2007 makes it easy to benefit from styles without having to know

much about them. However, you may want to know how styles work behind the scenes,

or you may want to know what's new with styles in Office Word 2007.

This article explains how styles work to save you time and make your document look

good, and it discusses the relationship between styles and two new features in Word

2007: Quick Styles and themes.

Styles save time and make your document look good

One of the great things about using a word processor is that you can create documents

that look professionally typeset.

Headings are in a font that contrasts with body text.

Paragraphs are separated with just enough white space.

Elements such as bulleted lists are indented.

Emphasized text is in a contrasting color.

The document may even include special elements such as a table of contents.



Format Text

You can format text in Microsoft Word by changing fonts, font size, and font style (bold,

italics, underline, etc.). Text formatting lets you add a professional look to your

documents. (Just be careful not to overdo it.)

Check spelling and grammar

Your Microsoft Office program provides tools that can help you correct mistakes. You

can check spelling and grammar in your files at the same time, or you can let the

Microsoft Office program suggest corrections automatically while you work.
