D X, You Fee Like a Musty Legend.

I used to be really pissed off about thisi i remember the feeling for astation. Why can we just like, multiply both sides by d x? Oh, ells, yes. The teacher kind of waves that over you where you ask, like and the x a ah. So they kind of do that. But if you do want to understand it more deeply, your choices are, ok, do this in my free time. It will require you learning a bunch of stuff or trying to get the teacher totoof explain the whole class.
