what exactly *is* a logarithm and what does it do?

1.04K viewsMathematicsOther

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 the good points made about exponents, logarithms have the extremely useful property of transforming multiplication and division into addition and subtraction. This is of keen interest to someone who has to do all their calculations by hand, since it’s easier to add than it is to multiply, and much easier to subtract than divide.
