In LaTeX it is coded as \cong. ∼ ∼ is a similarity in geometry and can be used to show that two things are asymptotically equal (they become more equal as you increase a variable like n n ). This is a weaker statement than the other two. In LaTeX it is coded as \sim. ≃ ≃ is more of a grab-bag of meaning.

https://simple.wikipedia.org/wiki/List_of_mathematical_symbols
The list below has some of the most common symbols in mathematics. However, these symbols can have other meanings in different contexts other than math. If x=y, x and y represent the same value or thing. If x≈y, x and y are almost equal. If x≠y, x and y do not represent the same value or thing. If x<y, x is less than y.

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 dot operator symbol is used in math to represent multiplication and, in the context of linear algebra, as the dot product operator. Typically, the symbol is used in an expression like this: 3⋅ 5. In plain language, this expression means three multiplied by five. The interpunct symbol also referred to as the middle dot, dot product symbol

https://simple.wikipedia.org/wiki/Equals_sign
The symbol used to say when items are not equal is "≠" (slashed equal sign). [1] There are several symbols that can be used to say items are " approximately the same," "similar to" or "about equal." Some of these symbols include: "≈" (two tildes or wavy lines, often used for "approximately equal") [1] "⩰" (two tildes above two lines)

Punctuation and parentheses rules. When it comes to parentheses and other punctuation, there are a couple of rules to follow. 1 If the text in parentheses is a complete sentence and is separate from surrounding sentences, the period goes inside the parentheses. Additionally, a phrase that could stand alone as a complete sentence can also be contained inside another complete sentence.

Multiplication and division, as well as addition and subtraction, hold an equal place in the order of operations, so you work these from left to right. In the problem above, after taking care of the subtraction in the parentheses, you need to first divide 5 by 5, yielding 1; then multiply 1 by 2, yielding 2; then subtract 2 from 9, yielding 7

Brackets are symbols used in pairs to group things together. When we see things inside brackets we do them first (as explained in Order of Operations ). The parentheses group 3 and 2 together, and 6 and 4 together, so they get done first: Without the parentheses the multiplication is done first: With more complicated grouping we can use

I think it's probably just notation to distinguish the ordering on F F from that on E E. Other acceptable symbols include ⪯ ⪯, ⊑ ⊑, etc. To explain what they mean by X ⪯ Y ⇔ X = X ∧ Y X ⪯ Y ⇔ X = X ∧ Y, they are referring to the Meet of X X and Y Y. You have x ∧ y = z ⇔ z ⪯ x x ∧ y = z ⇔ z ⪯ x and z ⪯ y z ⪯ y.

Here, the tilde indicates that 3.14 is an approximation of π. To wrap up, the ∼ symbol is versatile and widely adopted in various mathematical contexts. Its usage mainly revolves around the concepts of similarity, equivalence, or approximation. It's an efficient way to convey these concepts without the need for verbose explanations.

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

$\begingroup$ An added note, since the wiki article does not mention it: one can look at ∈ meaning 'is' through the prism of sets representing the common property held by all its elements. e.g. Even = {0,2,4,..} and 'a ∈ Even' can be read as 'a is Even' $\endgroup$
