I just found out what the determinant really means! It's not just a bunch of numbers, it's the absolute value of the parallelogram whose sides are the vectors involved! Why don't they tell us these things when we first learn the operations? This is like doing derivatives for years before finding out that they are the tangents.
Thank you, MIT!
And if you're not as excited as I am, well, that's perfectly okay. Just wanted to share...
