Midnight Commander using box-drawing characters in a terminal emulator. Box-drawing characters, also known as line-drawing characters, are a form of semigraphics widely used in text user interfaces to draw various geometric frames and boxes. These characters are characterized by being designed to be connected horizontally and/or vertically with ...
propositional logic, Boolean algebra, first-order logic. ⊥ {\displaystyle \bot } denotes a proposition that is always false. The symbol ⊥ may also refer to perpendicular lines. The proposition. ⊥ ∧ P {\displaystyle \bot \wedge P} is always false since at least one of the two is unconditionally false. ∀.
Tombstone (typography), the end of proof character. Geometric Shapes Extended (Unicode block) Miscellaneous Symbols and Arrows (Unicode block) includes more geometric shapes. Miscellaneous Symbols and Pictographs (Unicode block) includes several geometric shapes of different colors. Mathematical operators and symbols in Unicode.
In the table below, the codes on the left produce the symbols on the right, but these symbols can also be entered directly in the wikitext either by typing them if they are available on the keyboard, by copy-pasting them, or by using menus below the edit windows.
Block Elements is a Unicode block containing square block symbols of various fill and shading. Used along with block elements are box-drawing characters, shade characters, and terminal graphic characters. These can be used for filling regions of the screen and portraying drop shadows. Its block name in Unicode 1.0 was Blocks.
Miscellaneous Symbols is a Unicode block (U+2600–U+26FF) containing glyphs representing concepts from a variety of categories: astrological, astronomical, chess, dice, musical notation, political symbols, recycling, religious symbols, trigrams, warning signs, and weather, among others.
U+00D7 × MULTIPLICATION SIGN. The division sign ( ÷) is a mathematical symbol consisting of a short horizontal line with a dot above and another dot below, used in Anglophone countries to indicate the operation of division. This usage, though widespread in some countries, is not universal and the symbol has a different meaning in other countries.
Mathematical operators and symbols are in multiple Unicode blocks. Some of these blocks are dedicated to, or primarily contain, mathematical characters while others are a mix of mathematical and non-mathematical characters. This article covers all Unicode characters with a derived property of "Math". [2] [3]
