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.

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 ...
What could ' mean in an algebraic formula? The context is that the formula is for calculating temperature at an interface between materials and the three symbol combination is: theta ' n The formula gets used at the interface between consecutive material layers and so I'm assuming it ' means something like 'at the layer in question' but I'm trying to get a more precise definition.
Set Symbols. A set is a collection of things, usually numbers. We can list each element (or "member") of a set inside curly brackets like this: Common Symbols Used in Set Theory
The = equals symbol is used to show that the values on either side of it are the same. It is most commonly used to show the result of a calculation, for example 2 + 2 = 4, or in equations, such as 2 + 3 = 10 − 5. You may also come across other related symbols, although these are less common: ≠ means not equal. For example, 2 + 2 ≠ 5 - 2.
T he language and vocabulary of mathematics contain a large amount of symbols — some being more technical than others. Like letters in the alphabet, they can be used to form words, phrases and sentences that would constitute a larger part of the mathematical lexicon. \[ \begin{gather*}x \longrightarrow x+1 \longrightarrow (x+1)^2 \longrightarrow (x+1)^2 \ge 0 \\ \longrightarrow \forall x \in ...
