Damn ragebait posts, it's always the same recycled operation. They could at least spice it up, like the discussion about absolute value. What's |a|b|c|?
What I gather from this, is that Geogebra is superior for not allowing ambiguous notation to be parsed 👌
Yeah! That's why I mentioned it, it was a fresh ambiguous notation problem that I've never encountered before. Discussions of "is it 1 or 9" get tiring quickly.
At least WA and others tell you how they interpret the input, instead of being a black box (until you get to the manuals). Even though it is obvious in hindsight, I didn't get why two calculators would yield different results; thanks!
Nice write-up.
