Symbol for irrational

Irrational numbers are usually expressed as R\Q, where the backward slash symbol denotes ‘set minus’. It can also be expressed as R – Q, which states the difference between a set of real numbers and a set of rational numbers. The calculations based on these numbers are a bit complicated. For example, √5, √11, √21, etc., are irrational.
