$\approx$ 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

https://en.wikipedia.org/wiki/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 types, many symbols are needed for expressing all mathematics.

https://wumbo.net/symbols/approximately/
The approximately symbol (≈) is used in math to indicate that two expressions are approximately equal to each other. Typically, the symbol is used in an expression like this: In plain language, this means that the constant π (pi) is approximately equal to the value 3.14. In reality, the value of the constant π is irrational and continues

65. The upside-down A symbol is the universal quantifier from predicate logic. (Also see the more complete discussion of the first-order predicate calculus .) As others noted, it means that the stated assertions holds "for all instances" of the given variable (here, s ). You'll soon run into its sibling, the backwards capital E, which is the

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://wumbo.net/symbols/dot-operator/
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

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.

3 Answers. Short answer: A ⊊ B A ⊊ B means that A A is a subset of B B and A A is not equal to B B. Long answer: There is some confusion on mathematical textbooks when it comes to the symbols indicating one set is a subset of another. It's relatively clear what the symbol " ⊆ ⊆ " means. This symbol is more or less universally understood
