VERBS IN THE NEWS: it doesn't ADD UP

We all know that when we add one to one, we get two.  We call this mathematical process addition.  But the verb "(to) add up" has an informal meaning: it signifies that the result makes sense.

We will often hear it doesn't add up", meaning that the results don'tmake sense. This can be used when referring to numbers or when referring to facts.

Let's begin with this: Many people are puzzled or irate as to why General Petraeus was forced to resign.  They say that the facts don't add up to such a great American general being forced to resign. It doesn't make sense that the general would be forced to resign.  They wonder what's the story behind the story. Read, for example, this news story:
