Yes, it does.
Yes, it does.
An accumulation point of a set is a point where every neighborhood contains at least one point from the set other than itself. For the set of irrational numbers, every real number (rational or irrational) is an accumulation point. This is because between any two real numbers, no matter how close, there are infinitely many irrational numbers, ensuring that any neighborhood around a real number contains irrational points.

The point on a number line that corresponds to a number is called an "ordered pair" of a real number.
