{{Main|Mathematical Alphanumeric Symbols|l1=Mathematical Alphanumeric Symbols (Unicode block)}}

The Mathematical Alphanumeric Symbols block (U+1D400&ndash;U+1D7FF) contains Latin and Greek letters and decimal digits that enable mathematicians to denote different notions with different letter styles. The reserved code points (the "holes") in the alphabetic ranges up to U+1D551 duplicate characters in the [[#Letterlike Symbols block|Letterlike Symbols block]].<ref> In order, these are: {{not a typo|ℎ / ℬ ℰ ℱ ℋ ℐ ℒ ℳ ℛ / ℯ ℊ ℴ / ℭ ℌ ℑ ℜ ℨ / ℂ ℍ ℕ ℙ ℚ ℝ ℤ}}.</ref>

==Characters in other blocks==

Mathematical characters also appear in other blocks. Below is a list of these characters as of Unicode version {{Unicode version|version=1516.10}}:

Line 104 ⟶ 103:

{|

| U+002B || {{Large|+}} || PLUS SIGN

|-

|- style="text-decoration: line-through; background: orange;"

| U+002D || {{Large|-}} || HYPHEN-MINUS<ref>As per [https://www.unicode.org/Public/1516.10.0/ucd/DerivedCoreProperties.txt Unicode 1516.10.0], the ASCII hyphen-minus is not a mathematical symbol. To express the minus sign in math, {{unichar|2212|minus sign}} is used instead.</ref>

|-

| U+003C || {{Large|&lt;}} || LESS-THAN SIGN

Line 123 ⟶ 122:

| U+00AC || {{Large|¬}} || NOT SIGN

|-

| U+00B0 || {{Large|°}} || DEGREE SIGN<ref>As per [https://www.unicode.org/Public/1516.10.0/ucd/DerivedCoreProperties.txt Unicode 1516.10.0], the degree sign is not a mathematical symbol, since it is a measurement unit symbol rather than a math symbol. Consistently, TeX packages support many non-math symbols. But this article is designed to cover only Unicode characters with a derived property of "Math".</ref>
