Example 1: Using Interval Notation to Express All Real Numbers Greater Than or Equal to a Use interval notation to indicate all real numbers greater than or equal to −2−2.Solution Use a bracket on the left of −2−2 and parentheses after infinity: [−2,∞)[−2,∞). The ...
Open interval notation: (a,b); Closed interval notation: [a,b]; and Half-open interval notation: (a,b] or [a,b). How to use this inequality to interval notation calculator? Here we explain how our inequality to interval notation calculator works: Start by choosing the calculator mode, ...
The open interval and closed interval are used in algebra to represent a range of numeric values. The open interval is represented as an algebraic expression a < x < b, and the closed interval is represented as an algebraic expression a < x < b. The open interval does not include the ...

Theorem 6.3.2. Let X be a subset of 𝒜. Then Isat(X) is tractable iff X is a subset of the ORD-Horn algebra (Definition 6.2.14), or of one of the 17 subalgebras defined below. Otherwise, Isat(X) is NP-complete. Proof. See [Krokhin et al., 2003]. Definition 6.3...
Finally, the empty interval is represented in C++ by the character string [empty] and has the same properties as the empty set, denoted in the algebra of sets. Any arithmetic operation on an empty interval produces an empty interval result. For additional information regarding the use of empty...
