1. In mathematics, brackets are used to indicate the order of operations in an equation. For example, (3 + 4) x 2 = 14.
2. In writing, brackets are used to enclose additional information or comments within a sentence. For example, "The concert (which was held outdoors) was canceled due to rain."
3. In programming, brackets are used to define the scope of functions, loops, and conditional statements. For example, in JavaScript, curly brackets {} are used to define the body of a function.
4. In citations, brackets are used to indicate that a word or phrase has been added to a quote for clarification or context. For example, "She [the teacher] explained the assignment in detail."
5. In music, brackets are used to indicate that a note or group of notes should be played together. For example, in sheet music, brackets may be used to indicate a chord.

Mathematical Operations:
- Brackets indicate the order of operations. For example, `(3 + 4) - 5` calculates`(3 + 4) = 7` first, then multiplies by 5.
Grouping:
- Brackets group expressions together, allowing for calculations to be performed on the group as a whole. For example, `(x + y) - (a + b)` calculates `x - a + x - b + y - a + y - b`.
Subscripts and Superscripts:
- Brackets are used to indicate subscripts and superscripts. For example, `x_i` represents the ith element of x, and `x^2` represents x squared.
Set Notation:
- Curly braces are used to enclose elements of a set. For example, `{1, 2, 3}` represents the set containing 1, 2, and 3.
Function Notation:
- Brackets are used to enclose the argument of a function. For example, `f(x)` represents the value of the function f at x.
Interval Notation:
- Brackets are used to define intervals. For example, `[a, b]` represents the interval from a to b, and `(a, b)` represents the interval from a to b (excluding a and b).
Programming Languages:
- Brackets are used in many programming languages for various purposes, such as:
- Parentheses: Enclose method calls, function arguments, and expressions.
- Square brackets: Access array elements, represent arrays or lists.
- Curly braces: Define code blocks, objects, and dictionaries.
Text Formatting:
- Brackets are used in some text formatting conventions:
- Angular brackets: `<` and `>` enclose HTML tags.
- Square brackets: `[` and `]` enclose Markdown links.
- Curly braces: `{ }` enclose placeholder text in templates.
Other Uses:
- In linguistic notation, brackets enclose phonetic transcriptions.
- In music notation, brackets indicate chords or overlapping notes.
- In design and engineering, brackets are used to indicate structural elements.
