Dang. Yes, they do... and I'm ashamed to say I've known about those for some
time, and neither myself nor several other folks never picked up on that. Drat.

Since that's the way numbers work, that's how I'd teach (more to the point
that's how I *have* taught this - 3-4-5 (& other) triangles like this entered
the piture long before studless parts. I've also used the 1.5-2-2.5 version of
this.

I don't have a big problem with using "m" or "modulus" (confusion with meters is
possible... but, sadly, perhaps only for kids in Europe, where they would also
realize immediately how silly that was). As to "stud" or "LDU", well... there
are no studs (even if we adults know they are the same thing, distance-wise),
and LDU is longer. Personally, I'll still call them studs (or even just a
unitless number... "hey can you hand me that 12 long axle?").
