As a kid who had a habit of reverse engineering shit, (malware analysis and ethical hacking my beloved) I genuinely don’t know you can reverse engineer an equation with a question and 4 answers, 3 of them which are wrong. Even with two questions, its still a crapshoot, and the amount of wrong to right answers seems a bit time consuming to use to try and figure out the real solution, much less the equation, in a reasonable amount of time needed to complete an exam.
That’s making more sense to me, but my view of reverse engineering is 100% tainted by my work in SRE and hacking.
I work in the same way, but I’ve kinda forgot about using a calculator since the last few math classes I took forbid using calculators
