Two things that don't commute, but get called addition in some languages: * String concatenation * Tuple concatenation Others?
@johnmyleswhite @rcalsaverini @fulmicoton but it's not good enough to call commutative "add" and non-com "multiply"; multiplying Z commutes!

@avibryant@rcalsaverini@fulmicoton That's true. We could get better notation. IIRC we wound up with this due to linear algebra. -
@johnmyleswhite@avibryant The noncommutative + notation has never bothered me in the languages where I've used it (R, Python, C# at least).

@avibryant@johnmyleswhite@rcalsaverini@fulmicoton eg, when I see 'ab' in an equation, I just know if it's a product, variable, etc. -
@drjerrynyc@avibryant@rcalsaverini@fulmicoton I think this is why debatably bad notation isn't much of a problem.

@avibryant@johnmyleswhite@rcalsaverini@fulmicoton the hard part of "good" math notation is that humans just handle ambiguity better.Thanks. Twitter will use this to make your timeline better. UndoUndo
