Nah, your explanation is more complete

Jesus christ I don't even know what a matrix is.

Well, I don't really know how to use them, so we're not that far apart.

It's just a square of numbers, like this:

|1 2 3|
|4 5 6|
|7 8 9|

Ok cool but what is it for and how do you use it and all

Depends, they have tons of applications. It's like asking what are numbers for

but for example, they serve to solve systems of equations, to treat data in tables (2-variables), they can represent transformations in geometry (rotations, dilations, ...), etc.

And as for using, you can add/substract them (if they are the same size i.e. same number of rows&columns), multiply them (the rule is a bit complicated, but it's easier than the rule for division of numbers XD), take their determinant (it's a number associated with each square matrix), and such.

(if you want we can go to the math thread and I show you examples, better to keep on-topic here)

Or you could sketch it out for him

Interesting drawing.

Someone once told me that when something goes into a black hole whatever is left comes out of a white hole (it was probably just a theory). That is what I see in that drawing (were the black hole becomes a white hole).
