Question 232893
 How do I know which way the ">" and "<" go?? 
And what would the answer be to this proublem... a over 2 < -9
--------------------
a < b means a is less than b
b>a means b is greater than a
----------------------------------
Your Problem:
(a/2) < -9
Multiply both sides by 2 to solve for "a":
a < -18
