Real Numbers
A real number is any number that can be placed on the number line, whether that be
negative or positive, fraction or decimal.

100 is not a whole number.
Read all the options before answering. −17-17 is... (a. an integer b. a rational number c.
a real number d. all of the above.)

In mathematics, a collection of numbers is referred to as a set*
Interval
An interval is a set of numbers between two specified values. An interval can be
visualized as a segment of the number line. The segment of the number line above that
falls between 11 and 22 is called an interval*.

Contains unconnected points
In mathematics, whole numbers, integers, and even integers are all examples of discrete
sets. These sets contain unconnected elements, with gaps between each value.
In statistics, some data sets will be discrete. Examples of discrete data sets are the
number of adults in a household, the results of rolling two dice, and number of
machines in operation, as these are distinct groups.
