The set notation for all real numbers is represented by the symbol “R” or “ℝ”. It is often written as a capital letter R enclosed in double-struck or blackboard bold font.
Another common notation is to use interval notation to represent all real numbers. In this notation, the set of all real numbers is represented as (-∞, +∞), where the symbol (-∞) denotes negative infinity and (+∞) represents positive infinity.
In summary, the set notation for all real numbers can be represented as:
