We can represent the set of all real numbers between 2 and 10 as follows using the set builder notation: A = {x : x ∈ R, x > 2 and x < 10 }. This is read as X is the set of all the real numbers greater than 2 and less than 10.For example, the reals can be constructed based on $\mathbb Q$ via Dedekind cuts, via nested intervals or via Cauchy sequences in $\mathbb Q$, and certainly there are even more approaches. But I doubt the anybody imagines a real number as a Dedekind cut or as an equivalence class of Cauchy sequences.Explanation: R usually denotes the set of Real numbers. ∈ denotes membership. So x ∈ R, means that x is a member of the set of Real numbers. In other words, x is a Real number.
