Do you pronounce ln(x) as log(x) or lun(x)

    Totally silly question really but I've always read ln as log as it is just log to the base e. All my A level students pronounce it 'lun' as that is what their teachers say. It's many years since I got my degree in maths but I'm sure we just called natural log, log! Am I wrong? I know a bit like Trigger once you get used to calling something by the wrong name it is hard to stop.

    Is ln(x) read as log x or lun x?

    I tend to say "natural log of x" (as I would usually associate "log" without a qualifier as log base 10) but if I need to abbreviate then I always say "L.N. of x". I don't think I've ever said "lun" and I don't recall anybody else I know using "lun" either - maybe it's a regional thing?

    I was taught and say El En most of the time and use log with those who are likely to go on to study mathematics at a good university. Have never said lun but am aware that this is a thing.

    I wouldn't say log as, at A level, this is normally taken to mean log to base 10. Most of my students seem to say lun so I go along with that to avoid confusion.

    I've always used El-En for natural logs since I was a student back in the 70s. My current A-level students seem to prefer "lin".
