Generally, three kinds of brackets are used in mathematics, Parentheses or Round Brackets, ( ) Curly or Brace Brackets { } Square or Box Brackets [ ]
They are parentheses, square brackets, curly brackets, and angle brackets.
There are four primary types of brackets. In British usage they are known as round brackets (or simply "brackets"), square brackets, curly brackets, and angle brackets; in American usage they are respectively known as parentheses, brackets, braces, and chevrons.
The notation may be a little confusing, but just remember that square brackets mean the end point is included, and round parentheses mean it's excluded. If both end points are included the interval is said to be closed, if they are both excluded it's said to be open.
{} are called braces or curly brackets; ⟨⟩ are called bra and ket or angular brackets.
When Is a Bracket called a Parenthesis? In American English, the term “parenthesis” is often used to refer to the punctuation mark that is more commonly known as the “round bracket” or “parentheses.” These are the curved marks ( ) that are used to enclose a word, phrase, or sentence within another sentence.
Parenthesis vs braces vs brackets
Round brackets () are used for methods. Square brackets [] are used for arrays. Curly brackets {} are used to set scope.
() are parentheses. They are used to supply additional information and comments to a sentence. [] are square brackets, which are used to supply context to a sentence with omitted information. {} are curly brackets, which don't have a literary use but are used in programming commonly.
These symbols are called brackets. Brackets in mathematics serve a very important purpose; these symbols help us group different expressions or numbers together. Brackets imply that the thing or expression enclosed by them is to be given higher precedence over other things.
In languages like C curly braces ( {} ) are used to create program blocks used in flow control. In Python, curly braces are used to define a data structure called a dictionary (a key/value mapping), while white space indentation is used to define program blocks.
[] are called brackets or square brackets; {} are called braces or curly brackets; ⟨⟩ are called bra and ket or angular brackets.

Parentheses and brackets are punctuation marks used to set apart certain words and sentences. Parentheses, ( ), are used to add extra information in text, while brackets, [ ], are used mainly in quotations to add extra information that wasn't in the original quote.
Brackets are symbols that we use to contain "extra information", or information that is not part of the main content. Brackets always come in pairs—an "opening" bracket before the extra information, and a "closing" bracket after it. There are two main types of bracket: round () and square [].
How to use braces { } Braces are used to group items or to show a relationship among lines, symbols, or formulas in mathematical, statistical, or chemical equations.
The tilde (~) is a Linux "shortcut" to denote a user's home directory. Thus tilde slash (~/) is the beginning of a path to a file or directory below the user's home directory. For example, for user01, file /home/user01/test. file can also be denoted by ~/test. file (when referenced by the logged in user01).
Math is an abbreviation of mathematics, which is a count noun in British English because there are different types of maths (geometry, algebra, calculus, etc.) and a mass noun that happens to end in an 's' in American English (like gymnastics in both dialects).
The main difference between the & and && operators is that the & operator is a bitwise operator, while the && operator is a logical operator. The & operator compares two values at the bit level, while the && operator compares two values logically.
They are used in mathematical expressions in many programming languages like python, java, C etc. / is known as division operator which performs division and % is known as modulus operator, it is used to find the remainder. For eg : We have two operands a = 9, b = 3, and result of a/b = 3 whereas result of a%b = 0.
() is a tuple: An immutable collection of values, usually (but not necessarily) of different types. [] is a list: A mutable collection of values, usually (but not necessarily) of the same type. {} is a dict: Use a dictionary for key value pairs.
In JavaScript, we use {} braces for creating an empty object. You can think of this as the basis for other object types. Object provides the last link in the prototype chain that can be used by all other objects, such as an Array. var obj_name = {}; JavaScript Object Declaration {}
What are square brackets? Square brackets, often just called brackets in American English, are a set of punctuation marks that are most often used to alter or add information to quoted material. Square brackets come in pairs as [ and ].
Parentheses, sometimes called round brackets or just brackets, are the most common brackets in business writing. Use round brackets (parentheses) to add extra information to a sentence. You can use dashes or commas instead of brackets in some instances.
