Explain how to order a set of real numbers?

By definition, we have to:

In mathematics, the set of real numbers (denoted by R) includes both rational numbers (positive, negative and zero) and irrational numbers.

The set of real numbers is in the following interval:

(-∞,∞)

The correct order is from the smallest number to the largest number.

Answer:

The order of the real numbers goes from least to greatest, respecting the following interval:

(-∞,∞)

Ordering the real numbers is a process of arranging them in a particular order either from smallest number to the largest number or largest to the smallest. For example a set of real numbers is given to be {25,6,115,27,15,18} Then, this set in not in a regular pattern, so we arrange in in an increasing order as {6,15, 18, 25, 27, 115}
