Symbol for the set of irrational numbers.
Let's consider the set of rational numbers $$\{ r \in \mathbb{Q} \mid r \ge 1 \text{ and } r^2 \le 29\}$$ The supremum of the set equals $\sqrt{29}$. Perhaps it is more interesting to show that there does not exist a supremum of this set in $\mathbb{Q}$. That is in some way obvious. But we may still play with it and show the following:
Number Theory #1| Symbols | What is the symbol for Irrati…The number Pi, symbolized by a Greek letter, has a constant value that approximately equals 3.14159.

Here are some more set builder form examples. Example 1: A = {x | x ∈ ℕ, 5 < x < 10} and is read as "set A is the set of all ‘x’ such that ‘x’ is a natural number between 5 and 10." The symbol ∈ ("belongs to") means “is an element of” and denotes membership of an element in a set. Example 2:A rational number is a number that can be written in the form p q p q, where p and q are integers and q ≠ 0. All fractions, both positive and negative, are rational numbers.
