Press the number associated with a symbol or use the
cursor keys
to select one and press .
The relationship between any two numbers, expressions, lists, or matrices can be
compared by selecting one of the options. A **true** will be returned
if the test is true and a **false** if the test is false. For example, the
test, `4 > 7`, returns a value of **false** since it is a false
statement. Tests can also be made on statements such as

x = 9 or `x < 2.5`

The result of such a test depends upon the value of the variable x.
This type of comparison is often used to control the domain
over which a graph is drawn.
