What are some common applications of real numbers?

At its core, a real number is any value that can be expressed on the number line, including both rational and irrational numbers. Rational numbers are values that can be expressed as a ratio of two integers, such as 3/4 or 0.75. Irrational numbers, on the other hand, cannot be expressed as a finite decimal or fraction and include values like the square root of 2 or pi. Real numbers can be added, subtracted, multiplied, and divided just like rational numbers, but they also include the concept of limits and infinite sets. For example, the number line is infinitely dense, allowing for an infinite number of values between any two real numbers.
