The installation of font files is also relatively simple: after downloading "symbol.ttf", double-click Install or Copy (CTRL+C) to copy the files to the system disk-usually the "C: \ Windows \ Fonts" folder. Flashes after the prompt "Installing font file ...", and the font is installed.
After installing the font, open the Word document, click Formula Editor, select Other under the Style menu in the Formula Editor state, select Computer Modern Font in the Other Styles dialog box, click OK, and finally enter the corresponding content in the Formula Edit box.
