In logic, a set of symbols is commonly used to express logical representation. The following table lists many common symbols, together with their name, how they should be read out loud, and the related field of mathematics.
It can signify exponentiation, the bitwise XOR operator, string concatenation [citation needed], and control characters in caret notation, among other uses. In regular expressions , the caret is used to match the beginning of a string or line; if it begins a character class, then the inverse of the class is to be matched.
Turned v (majuscule: Ʌ, minuscule: ʌ) is a letter of the Latin alphabet, based on a turned form of the letter V. It is used in the orthographies of Dan , Ch’ol , Nankina , Northern Tepehuán , Temne , Oneida , and Wounaan and also some orthographies of Ibibio .

Ceiling function : if x is a real number, ⌈ x ⌉ {\displaystyle \lceil x\rceil } is the lowest integer that is not lesser than x .
The V sign, a symbol representing peace among other things The vertically reflected symbol, ∧, is a wedge , and often denotes related or dual operators. The ∨ symbol was introduced by Russell and Whitehead in Principia Mathematica , where they called it the Logical Sum or Disjunctive Function .
