What if mathematical symbols are not displayed in Formula Editor and Word?
The following problems may exist. Formula Editor will not be installed in a typical installation of word. To choose a custom installation, select Word Formula Editor 3.0. \x0d\\x0d\ If you keep the installation file, you can install it as follows: \x0d\ Click the control panel, click Add and Remove Programs, find the uninstaller of Microsoft Office Professional Edition (this was the case in 2003, and different versions are different), and select "Change"-"Add or Remove Functions", and the check mark before the installed program remains unchanged. Next, select "Select Advanced Customization of Application" at the bottom left. Next, under advanced customization, find the OFFICE tool, as shown in word Formula Editor 3.0, and right-click and select Run on this machine. \x0d\\x0d\ Double-click the mathematical formula that shows the problem, and the formula editor will start automatically. Click Style-Definition in the Formula Editor interface, and click Advanced in the pop-up Define Style dialog box. At this time, you can see the font settings of the formula editor, paying special attention to the settings of variables, lowercase Greek letters and symbols. If your system does not support this font, the formula editor will not be able to display mathematical formulas correctly. \x0d\\x0d\ You can select the font you like and have installed in your system in the corresponding drop-down list box, so that it can be displayed correctly after setting and entering the formula. It is suggested to use "Times New Roman" font for variables and "Symbol" font for lowercase Greek letters and symbols. General windows systems install these two fonts by default. \x0d\\x0d\ If what you see in Word is garbled, but what you see after entering the formula editor is a correctly displayed formula, it will become garbled after exiting the formula editor. In fact, this is because the formula is automatically displayed in the font supported by your system in the formula editor, but it is not updated in the word document. At this time, you just need to click "File-Update Document?" In the Formula Editor. Or press the shortcut key "Ctrl+S" to update the formula font to the document, and then you can see that the formula has been displayed normally after exiting.
