$\approx$ 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://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

https://wumbo.net/symbols/greater-than-or-equal/
The greater than or equal to symbol is used in math to express the relationship between two math expressions. Typically, the symbol is used in an expression like this: a ≥ b. In plain language, this expression represents that the variable a is greater than or equal to the variable b. The greater than or equal to symbol is used in math to

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

Even the most sophisticated mathematical equations rely on a handful of fundamental common math symbols. Before you can solve the mystery of the Collatz Conjecture, figure out a square root or understand more complex algebraic symbols, you'll need to master the basic mathematical symbols that are necessary for writing a mathematical equation.

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/Plus_and_minus_signs
The plus sign (+) and the minus sign (−) are mathematical symbols used to denote positive and negative functions, respectively. In addition, + represents the operation of addition, which results in a sum, while − represents subtraction, resulting in a difference. Their use has been extended to many other meanings, more or less analogous. Plus and minus are Latin terms meaning "more" and

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
