5.4 Solving Equations with Infinite or No Solutions
... When does three equal three? All the time! This means that it doesn’t matter what value we substitute for , the equation will always be true. Go ahead and try plugging in a couple of your favorite numbers to verify this is true. Also note that twice a number plus three is equal to itself in our ori ...

... that also ρ = 1.57. For that reason, (7) represents that number with an infinite succession of 0,s, that is, ρ = 1.57 = 1.5700 · · · . The reason for this resides in that an infinite succession of 9’s is ruled out by the condition of the theorem that bi < ai − 1 for infinitely many i, a condition th ...

Infinity
Infinity (symbol: ∞) is an abstract concept describing something without any limit and is relevant in a number of fields, predominantly mathematics and physics.In mathematics, ""infinity"" is often treated as if it were a number (i.e., it counts or measures things: ""an infinite number of terms"") but it is not the same sort of number as natural or real numbers. In number systems incorporating infinitesimals, the reciprocal of an infinitesimal is an infinite number, i.e., a number greater than any real number; see 1/∞.Georg Cantor formalized many ideas related to infinity and infinite sets during the late 19th and early 20th centuries. In the theory he developed, there are infinite sets of different sizes (called cardinalities). For example, the set of integers is countably infinite, while the infinite set of real numbers is uncountable.
