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

As it stands, there're a few non-gismu solutions, such as {s= elsumji}. Indeed, cleverly rearranging the places of a sum produces a diffe= rence 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 opera= tor, 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: semantical= ly, it isn't purely mathematical. The other three are clearly definitely ma= thematical, 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 simp= ly made up for this rather than try to find other solutions. I (na=C3=AFvel= y) suggest {subja}, with -sub- from English & romlang "subtract" and -j= a- from Mandarin "ji=C7=8En".

.ienai when jian3 was chosen fo= r {jdika} it was nearly okay. but "jian3" for sure should be converted to l= ojban as "dzian" or "dian". however, you chose {ja} which in Mandarin will = be "ra". So whats the advantage of importing mnemonics that wont work at al= l?

Next, why you choose the gloss "to subtract". W= hats the proposed definition?

x1 is a difference/result of subtra= ction of x3 from x2 ?

Then the glossword should be= "difference"

As for Mandarin it is cha1shu4

Of cou= rse we can play with the sounds a bit but in order to get a better mn= emonic we have to choose either chinese or romance etymology.

So = I suggest either {tcacu}/{tcaco} (.uinaisai it clashes with {tcaci}) or {di= fro} (final -o is normal for mekso gismu).

However= , selsumji seems fine to me. But if you do really want to add it to jvs ple= ase consider that jian3 is not suitable.

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

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