It is all trivial bro. There is no reason to do that, all your doing is plugging numbers into an equation, manipulating an equation so that you solve for whatever variable you want, or deriving variables from given information using a formula. Which btw can be very hard, not trying argue that. However all of this can be done in seconds with 100% accuracy using a computer, what is the point of showing pages of work showing how units cancel and how you got x by itself when you can skip the crap and get the value just by pushing a few buttons.
I mean I suppose you can argue that you need to know these steps in order to analyze the data your given, but idk I am not an engineering major. But what I will say for chemistry half of the shit I do I really have no idea why i am doing it when in any real world setting I would never do it using the methods I have to on an exam. So instead of focusing on the theory behind what is being done, I am just trying to get an answer that I really don't know what it is used for.
