back and forth, forever.
Unfortunately some calculators, such as Google’s will ignore your brackets and put in their own anyway. You just gotta find a decent calculator in the first place.
It is also frustrating when different calculators have different orders of operations and dont tell you.

Yeah, but to be fair most of them do tell you the order of operations they use, they just bury it in a million lines of text about it. If they could all just check with some Maths teachers/textbooks first then it wouldn’t be necessary. Instead we’re left trying to work out which ones are right and which ones aren’t. Any calculator that gives you an option to switch on/off “implicit multiplication”, then just run as fast as you can the other way! :-)
As a software developer, the less ambiguous your notation is, the better it is for everyone involved. Not only will I use brackets, I’ll split my expression into multiple rows and use tabs to make it as readable as humanly possible. And maybe throw a comment or 2 if there’s still some black magic involved
I genuinely hate being human for this stuff. So many things have such crazy computational shortcuts, it’s sometimes difficult to remember which part represents reality. Outside of the realm of math, where “imaginary” numbers are still a touch of enigma to me, so many algorithms are based on general assumptions about reality or the specific task, that the programmatic approach NEVER encapsulates the full scope of the problem.
As in, sometimes if you know EXACTLY how a tool works, you might still have no idea about the significance of that tool. Even in a universe where no one is lazy, and everyone wants to know “why?”, the answers are NOT forthcoming.
