    bro some teachers really do be wild.. they could literally just discuss one lesson like “what’s an atom” and what appears on the test is “explain the entire existence of the universe using the mass of the sun”

    I don’t know how to plug that in to my calculator. I’d like to know how to do this without a fancy calculator with my brain or at least what buttons to hit. I just need the angle for a project but everyone uses a calculator and doesn’t explain how to use the stupid thing. Not fresh out of high lol it’s been a couple of decades.
