Comparisons:

two values can be compared using relational operators.

relational operators:

==	equal to	!=	not equal to
<	less than	<=	less than or equal to
>	greater than	>=	greater than or equal to

The condition must be enclosed in parentheses!

examples:

(allowance <= expense)

(age != 21)

(age == 18)

ex .

allowance>=expense

age!=21

age==18
