Below is a list of these characters as of Unicode version 15. Most of the basic notation for matrices and vectors in use today was available by the early 20 th century. For vector analysis words see here vector analysis symbols are on the calculus page. Mathematical characters also appear in other blocks. For matrix and vector entries on the Words pages, see here for a list. The Arabic Mathematical Alphabetic Symbols block (U+1EE00–U+1EEFF) contains characters used in Arabic mathematical expressions.Īrabic Mathematical Alphabetic Symbols Main article: Arabic Mathematical Alphabetic Symbols block Miscellaneous Symbols and Arrows Ĭombining Diacritical Marks for Symbols block Any number bigger than zero is a positive number and can be written with or without a plus sign in front of it. The math subset of this block is U+2B30–U+2B44, U+2B47–U+2B4C. This page lists basic maths symbols with their names and examples in English. The Miscellaneous Symbols and Arrows block (U+2B00–U+2BFF Arrows) contains arrows and geometric shapes with various fills. Main article: Miscellaneous Symbols and Arrows (Unicode block) ^ Unicode code points U+2329 and U+232A are deprecated as of Unicode version 5.2 The Miscellaneous Technical block (U+2300–U+23FF) includes braces and operators. Main article: Miscellaneous Technical (Unicode block) ^ Grey areas indicate non-assigned code points The reserved code points (the "holes") in the alphabetic ranges up to U+1D551 duplicate characters in the Letterlike Symbols block. The Mathematical Alphanumeric Symbols block (U+1D400–U+1D7FF) contains Latin and Greek letters and decimal digits that enable mathematicians to denote different notions with different letter styles.
