In mathematics, brackets of various typographical forms, such as parentheses ( ), square brackets [ ], braces { } and angle brackets , are frequently used in mathematical notation. Generally, such bracketing denotes some form of grouping: in evaluating an expression containing a bracketed sub-expression, the operators in the sub-expression take precedence over those surrounding it. Se hela listan på overleaf.com Parentheses in domain mean exclude, square brackets mean including If you have infinity or negative infinity, the corresponding sign needs to be parentheses.

### Square brackets in group theory. My Algebra teacher uses notation I'm not familiar with, googling didn't really help. For example, f is a group homomorphism

Dive into the history and uses of [ ], { }, ? ?, and ( ) with Thesaurus.com. A parenthesis - (or ) - means that end is exclusive and doesn't contain the listed element. So for [first1, last1), the range starts with first1 (and includes it), but ends just before last1. Assuming integers: (0, 5) = 1, 2, 3, 4 (0, 5] = 1, 2, 3, 4, 5 [0, 5) = 0, 1, 2, 3, 4 [0, 5] = 0, 1, 2, 3, 4, 5 Parentheses are also used to set apart the arguments in mathematical functions. For example, f(x) is the function f applied to the variable x. In coordinate systems parentheses are used to denote a set of coordinates; so in the Cartesian coordinate system (4, 7) may represent the point located at 4 on the x-axis and 7 on the y-axis.
