Mathematical fonts. In mathematical mode you can change the typefaces of the fonts when needed. For instance, it's customary to represent real numbers with a blackboard bold font, or topological spaces with calligraphic font. This article shows several fonts in math mode.
Typefaces (often called type families or font families) are collections of fonts that share an overall appearance, and are designed to be used together, such as Adobe Garamond. A type style is a variant version of an individual font in a font family.f the font family you chose does not include a bold or italic style, click the Faux Bold button or the Faux Italic button in the Character panel to apply a simulated style.
