I'll put it in a food analogy, so you monkey 4channer brain can understand it.
Linear algebra are like vegetables. When you are young and inexperienced, you eat them because your parents make you to. The older you get and more experience you gather, the more you learn to appreciate them and why your parents made you eat them.
So eat you veggies, Anon. You can thank us, after they have made you a strong and healthy adult.
