Ok so officially a matrix is a rectangular array of numbers, symbols, etc arranged in rows and columns that is treated in certain prescribed ways. But that doesn't help me understand a darn thing. From what I understand, a matrix is a math tool that can help you solve linear systems, represent tables, and represent vectors (that's another whole confusion in it of itself for me). Like when I'm working with real life, where do I see something and say, "oh, that's a matrix!!!"? I can go outside and see real life events and say "oh, I can represent that as a function!!!!". How does one go about doing that with matrices? I personally wish someone would explain to me what a matrix is in simple layman's terms.
