Well, right from the start we know that <em>-23 isn't greater than +23</em> for obvious reasons. <em>-23 is less than +23</em> for even more obvious reasons. But when you think about it, <em>-23 and +23 could be equal to each other</em>. The reason for this is because <em>the absolute value of -23 is +23</em>.
Now this might not be 100% accurate and I apologize for that.
