To be fair, it's a text book. However, the next nearest non-text book had something about dodecahedrons on page 52, so there's clearly no hope for me.

OK, so you have different types of equations, probably you remember quadratic equations from school? In those you have a term like x squared.

A linear equation doesn't have any of these squared terms or anything in it. All the x, y's and z's are all just in that form.

So this is a linear equation: 2x + 3y + 7z +3 = 0

With the Gaussian stuff, you might have a whole load of these, and you have use some mathematical jiggery-pokery (Gaussian Elimination) to work out the terms. Most times it's pretty straightforward, quite logical. But sometimes the numbers go a bit mental.

It’s real easy to say you’re 100% against abortion when you’ll never have to make that decision.
