[[File:UCB_Miscellaneous_Mathematical_Symbols-B.png | thumb | right | Graphical representation of the Miscellaneous Mathematical Symbols-B Unicode block]]
'''Miscellaneous Mathematical Symbols-B''' is a [[Unicode block]] containing miscellaneous mathematical symbols, including brackets, angles, and circle symbols.

==Block==
{{Unicode chart Miscellaneous Mathematical Symbols-B}}


Some of these symbols are used in [[Z notation]]. Specifically 
*{{unichar|2981|Z NOTATION SPOT}}
*{{unichar|2982|Z NOTATION TYPE COLON}}
*{{unichar|2987|Z NOTATION LEFT IMAGE BRACKET}}
*{{unichar|2988|Z NOTATION RIGHT IMAGE BRACKET}}
*{{unichar|2989|Z NOTATION LEFT BINDING BRACKET}}
*{{unichar|298A|Z NOTATION RIGHT BINDING BRACKET}}
The last two symbols are used in [[Tiny and miny|combinatorial game theory]] 
*{{unichar|29FE|TINY}}
*{{unichar|29FF|MINY}}
