$\approx$ is used mostly for the approximate (read: calculated) value of a mathematical expression like $\pi \approx 3.14$ In LaTeX it is coded as \approx. $\cong$ is used to show a congruency between two mathematical expressions, which could be geometrical, topological, and when using modulo arithmetic you can get different numbers that are congruent, e.g., $5 \text{ mod } 3 \cong 11 \text

Glossary of mathematical symbols. A mathematical symbol is a figure or a combination of figures that is used to represent a mathematical object, an action on mathematical objects, a relation between mathematical objects, or for structuring the other symbols that occur in a formula. As formulas are entirely constituted with symbols of various

The nullish coalescing operator can be seen as a special case of the logical OR ( ||) operator. The latter returns the right-hand side operand if the left operand is any falsy value, not only null or undefined. In other words, if you use || to provide some default value to another variable foo, you may encounter unexpected behaviors if you

https://en.wikipedia.org/wiki/Multiplication_sign
The multiplication sign (×), also known as the times sign or the dimension sign, is a mathematical symbol used to denote the operation of multiplication, which results in a product. While similar to a lowercase X (x), the form is properly a four-fold rotationally symmetric saltire.. The symbol is also used in botany, in botanical hybrid names and the heavy goods vehicle industry, to calculate

The quotation marks symbol is a type of punctuation used for setting words and passages apart from the rest of the text. Quotation marks, or "quotes" for short, look just like commas, except quotation marks are at the top of a line instead of at the bottom. Double quotation marks are simply two "commas" next to each other, while single

Because some operators are used so frequently in logic and mathematics, we give them names and use special symbols to represent them. The conjunction of the statements P and Q is the statement " P and Q " and its denoted by P ∧ Q. The statement P ∧ Q is true only when both P and Q are true. The disjunction of the statements P and Q is

https://en.wikipedia.org/wiki/Bracket_(mathematics)
In elementary algebra, parentheses ( ) are used to specify the order of operations. Terms inside the bracket are evaluated first; hence 2×(3 + 4) is 14, 20 ÷ (5(1 + 1)) is 2 and (2×3) + 4 is 10. This notation is extended to cover more general algebra involving variables: for example (x + y) × (x − y).Square brackets are also often used in place of a second set of parentheses when they

The one inarguably acceptable use of the slash in formal writing pertains to poetry. The slash, with one space on either side, indicates a line break. In choosing your path in life, you might consider the words of Robert Frost, in his poem "The Road Not Taken": "I took the one less traveled by, / And that has made all the difference.".

https://mathworld.wolfram.com/Parenthesis.html
One of the symbols ( or ) used to denote grouping. Parentheses have a great many specialized meanings in mathematics. A few of these are described below. 1. Parentheses are used in mathematical expressions to denote modifications to normal order of operations (precedence rules). In an expression like (3+5)×7, the part of the expression within the parentheses, (3+5)=8, is evaluated first, and

That's the negative 9 plus the 6, and that is equal to 12x plus 18. Now, we want to group all the x terms on one side of the equation, and all of the constant terms-- the negative 3 and the positive 18 on the other side-- I like to always have my x terms on the left-hand side, if I can. You don't have to have them on the left, so let's do that.

There are three commonly used means of indicating multiplication. The symbol " x ", e.g., 5 x 6 = 30. Note that this symbol is generally avoided in algebraic equations because of the common use of "x" to indicate an unknown quantity. The symbol " * ", e.g., 5 * 8 = 40. The use of the asterisk to indicate multiplication is commonly used in

It can mean "is defined to be equal to" (for which another common symbol is := := ). Another meaning is "is identically equal to" (for example we write sin2 x +cos2 x ≡ 1 sin 2. ⁡. x + cos 2. ⁡. x ≡ 1 to emphasize that this equation holds for all x ∈R x ∈ R (actually for all x ∈C x ∈ C as well)). It can also mean congurence as
