What's so great about using a Matrix? It's a freaking table what's the difference?? :( They say there is but I don't get it.

It's a graphic way to show mathematics information.

It's sort of like diagramming sentences--a graphic way to show the parts of speech.

They're tables which can be operated on and can set up linear equations and have a whole host of other uses.

It is just "another way of showing numbers" but it's incredibly powerful.
