Bold italics of Greek characters; Bold and heavy styles of basic math symbols; AMS symbols, including bold and heavy styles; Script, blackboard bold, and "holey Roman" (seriffed blackboard bold) fonts; MathTime has its own license (i.e., unrelated to the license of Times New Roman). [11]
Actual bold fonts are designed with some features thicker and others the same size as a regular font, so the use of this "fake bold" is considered undesirable from a typographic point of view. [citation needed] Overstriking with an offset was also used to created "Blackboard bold" style characters used in mathematics. [4]
The set of real numbers, sometimes called "the reals", is traditionally denoted by a bold R, often using blackboard bold, . [2] [3] The adjective real, used in the 17th century by René Descartes, distinguishes real numbers from imaginary numbers such as the square roots of −1. [4]

A split-complex number is an ordered pair of real numbers, written in the form = + where x and y are real numbers and the hyperbolic unit [1] j satisfies = + In the field of complex numbers the imaginary unit i satisfies =
Another use of the Iverson bracket is to simplify equations with special cases. For example, the formula (,) = = is valid for n > 1 but is off by 1 / 2 for n = 1.To get an identity valid for all positive integers n (i.e., all values for which () is defined), a correction term involving the Iverson bracket may be added: (,) = = (() + [=])
