I mean, I’ve used them in algebra many times but I never really understood what it does. Kinda like in biostatistics how I could do the math, but how it worked was beyond me entirely.
So yeah: like what’s this sorcery and what does it do/why do we use it?

In addition to what others have said, it can be thought of as repeated division.
To calculate log base 2 of sixteen, divide by two repeatedly, until you get to one. It take 4 times, so log base 2 of 16 is 4.
I hate that some people just treat it like some sort of magic trick that undoes exponents.
