Microsoft Word 2000 has a little-known calculator that you can add to a toolbar. It's quick and handy to use for any simple on-screen calculations in a Word document. Use the following steps to add the Tools Calculate tool:

1. Choose Tools, Customize, Command tab.

2. In the Categories list, select Tools.

3. In the Commands list, find the Tools Calculate command (toward the bottom) and click on it.

4. Drag and drop the Tools Calculate command into any toolbar.

5. The button appears grayed out until you select an equation.

Now you're ready to test it. Type an equation, select it, and click your new Tools Calculate button. The answer appears in the status bar at the bottom of the window and gets copied automatically onto the clipboard. Just click Ctrl+V to insert the answer where you want it. (Remember, use an asterisk * for multiplying, a slash / for division, a hyphen - for a minus sign, and a plus sign + for you know what.)
