Thanks for putting my thoughts into words, that's exactly why I hate math. It was supposed to be the logical one, but since it only needs to be parsed by humans it failed at even that. It's just conventions upon conventions to the point where it's notably different from one teacher/professor to the next.
I guess you can tell why I went into comp-sci (and also why I'm struggling there too)
Hardware bring up is when you design a pcb or something and there doesn't yet exist any firmware for it. It would be the ability to debug the board and write firmware for it.

No but seriously, why do you think it necessarily needs to be different? There are calculators that use actual fraction notation and all that
