The operator, when given the same function, returns the maximum value of the function instead of the point or points that cause that function to reach that value; in other words max x f ( x ) {\displaystyle \max _{x}f(x)} is the element in { f ( x ) : f ( s ) ≤ f ( x ) for all s ∈ S } . {\displaystyle \{f(x)~:~f(s)\leq f(x){\text{ for all ...

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]
