Basic Math/Math


What are the rules for using symbols ">" and "<" (expressing greater than/less than)?  What does it say or mean when a number precedes or follows each symbol (e.g., "a>" or ">a")?  What does "a>b" mean?

As you pointed out, it means one number is greater than or less than another.  In your example, a is greater than b.  The way I like to remember what each means is that the smaller number is at the point (the small end of the symbol) and the larger number is at the open end (the larger side) of the symbol.  In reading, you always read left to right, so a > b is a is greater than b.  b < a is b is less than a.  Both statements say the same thing in reality, it's just a matter of how it's written.  So, in your example, a>b if b = 2, then a is 3 or morer.  In b<a, if a=2, the b is 1 or less.
