Why did I create a Lemmy world account as opposed to beehaw or ml? Because it's the first one I saw. Because it doesn't matter. Because I don't know what ml stands for. Because Lenny world said "general use." Because I didn't have to fill out an application. Because I can still interact with everything else, and again, it doesn't matter.
There's quite a few calculators that get this wrong. In college, I found out that Casio calculators do things the right way, are affordable, and readily available. I stuck with it through the rest of my classes.
