Generally speaking, there are not many font files for editing mathematical formulas, but even some commonly used font files may not be installed in your system due to system installation. Usually, the default variable of windows system uses "time". New? Roman font, lowercase Greek letters and Symbols all use Symbol font, which is the lack of symbol font in the above situation. The solution is that after downloading the "symbol" font, you can click the download site to download the font for you, and then copy and paste it under C:\\WINDOWS\\Fonts (copy and paste whether there is one or not).

If the font file still can't solve the problem after installation (there is no problem with the display of general mathematical symbols, but the formula edited by the formula editor is still displayed as garbled), it is necessary to check whether there is any problem with the setting of mathematical fonts in your formula editor. First, open the test paper (or courseware), double-click the mathematical formula that shows the question, and then the formula editor will start automatically. Click "Style-Definition" in the formula editor interface.

In the pop-up "Definition? In the Style dialog box, click Advanced to 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 cannot display the mathematical formula correctly. The easiest way is to click "Factory Settings" on the right to restore to the default settings. Of course, you can also select the font you like and install in your system in the corresponding drop-down list box, so that it can be displayed correctly after setting and entering the formula.

Sometimes what you see in Word is garbled, but what you see after entering the formula editor is the correctly displayed formula, and then it becomes 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 only need to click "File-Update Document ..." or press the shortcut key "Ctrl+S" in the formula editor to update the formula font into the document. After exiting, you can see that the formula has been displayed normally.
