I'm nearly certain this has been remarked on in the past, but there appears
to be no gismu for "difference" in the mathematical sense. This is pretty
inconsistent, as there're gismu for the other three basic mathematical
operators, namely {sumji}, {pilji}, and {dilcu}, for sum, product, and
quotient, respectively.

As it stands, there're a few non-gismu solutions, such as {selsumji}.
Indeed, cleverly rearranging the places of a sum produces a difference in
much the same way as doing so to the places for a product produces a
quotient. Why, then, should {dilcu} and not <difference> exist?

If we consider that {vu'u}, the mekso subtraction operator, is based on
{vimcu}, we can try to make a subtraction selbri from it. First, we need to
remove the agent with zil-, then we need to convert the (thus) x3 with
ter-: {terzilvi'u}.

{terzilvi'u} has one obvious problem though: semantically, it isn't purely
mathematical. The other three are clearly definitely mathematical, whereas
{vimcu} is used for any partial removal of something. "Getting a haircut"
is phrased in terms of {vimcu}.

It seems like it'd add consistency if a gismu were simply made up for this
rather than try to find other solutions. I (na=C3=AFvely) suggest {subja}, =
with
-sub- from English & romlang "subtract" and -ja- from Mandarin "ji=C7=8En".

subja =3D x1 is the difference, x2 minus x3

If there were other suggestions for a potential gismu for this in the past,
I'd like to know them. If there were none, I'll probably add this to
jbovlaste within a few days.
