The formulas in the Word2010 document also have some characteristics of plain text, so the user can set the font, font size, color, bold, italic, and so on for the formula.
The default font for Word2010 formulas is Cambria Math, which is the only font in Word2010 that fully supports all mathematical symbols in the Equation Editor, so it is recommended that you use this default font if there are no special requirements. In addition, the letter format in the Word2010 formula is skewed by default. For font size, color, and bold formatting, you can select the entire formula or individual characters in the Font group in the start Ribbon, as shown in Figure 1.
