In algebra, constants are symbols used to denote key mathematical elements and sets. The following tables document the most common of these — along with each symbol’s name, usage and example. (For common constants in general, see common math constants .)
1. Between two numbers, either it is used instead of ≈ to mean "approximatively equal", or it means "has the same order of magnitude as". 2. Denotes the asymptotic equivalence of two functions or sequences. 3. Often used for denoting other types of similarity, for example, matrix similarity or similarity of geometric shapes. 4.

mathematics is to use the “tombstone” in place of “QED”. This “tombstone” notation is attributed to the great mathematician Paul R. Halmos (1916– 2006). Some Notation from Set Theory ⊂ (the is included in sign) means “this set is a subset of” and ⊃ (the includes sign) means “this set has as a subset”.
