Yes.
All irrational numbers are non-recurring. If a number is recurring, it is rational. Examples of irrational numbers include the square root of 2, most square roots, most cubic roots, most 4th. roots, etc., pi, e, and most calculations involving irrational numbers.
Real numbers
They are irrational numbers!
the set of real numbers
All rational and irrational numbers are real numbers.
All irrational numbers are not rational.
All irrational numbers are real, but not all real numbers are irrational.
-- There's an infinite number of rational numbers. -- There's an infinite number of irrational numbers. -- There are more irrational numbers than rational numbers. -- The difference between the number of irrational numbers and the number of rational numbers is infinite.
No. All irrational numbers are real, not all real numbers are irrational.
Irrational numbers are infinitely dense so it is not possible to list them. Whatever positive irrational number you select, there are infinitely many smaller ones.
Ye it is true that all irrational numbers are real numbers that can't be expressed as fractions.
All natural numbers are rational numbers. No irrational numbers are natural numbers.
There are infiitelt many subsets of irrational numbers. One possible subset is the set of all positive irrational numbers.
No. No irrational numbers are whole, and all whole numbers are rational.
No. Irrational numbers form a proper subset of real numbers. That means that all irrationals are real so non-reals cannot be irrational.
It is impossible to list all the digits of π as they go on forever without repeating - π is an irrational number (in fact it is a transcendental number which is a special kind of irrational number). π starts 3.1415926535897932384626433832795028841971693993...
