I am guilty of having taught that to a five year old during a hiking trip. He is now an engineer.

I taught a 5 year old that 1 + 1 = 10, and they got in trouble at school for arguing with the teacher. Even after explaining that 1 + 1 = 10 in binary specifically, as the teacher was complaining to the parents "whatever that means". The parents asked me to be more careful with my "teaching".

  I get your teacher was dumb, but technically it could be on the right side. It all depends on whether you were writing it or saying it, "1 + 1 = 10" is true in binary but "one plus one equals ten" is not, not even in binary.

    >I get your teacher was dumb, but technically it could be on the right side. Let's be fair, a 5 year is only in kindergarten, so I would not expect a kindergarten teacher to be fully expecting a 5 year old to be talking about binary or even fully educated in other counting methods than base 10. That doesn't make them dumb. I'm sure that teacher could teach you things without calling you dumb.

      Err... sorry I don't know said teacher, I was just following along your comment, where you seem to portray the teacher in such way. You even do it in this comment, condescendingly, >I would not expect a kindergarten teacher to be [...] fully educated in other counting methods than base 10 Honestly, it's not that big of a deal to know binary or not. But anyway, that aside, you completely missed the point of my comment. Whew.

        Are you saying that my not expecting a kindergarten teacher to be educated in binary math is condescending? I got your point that 10 in binary is not actually base 10 10, but 2 in base 10. It was just not worth commenting as it was a discussion about a 5 year old conversation not the semantics of math.

        I mean, I'd want my kindergarten teacher to be focused teaching kindergarteners. I don't want them to be an expert on calculus, just be the best teacher for a kindergartener. Same thing as "i want my IDE to focus on being an IDE, and not add facebook integration". I feel like making sure the absolute fundamentals are well ingrained in your kid is way more important than trying to teach them binary. Important stuff like learning the alphabet. How to read simple books. Things like that.

        That was my point. Expecting a kindergaten teacher to do anything beyond those things you listed is not reasonable. It's great if after teaching a day of kindergartners they can then do an evening teaching college classes, but that's so not the norm. Stating that a teacher at this level is not fully versed in binary is not an insult. It's more insulting to think that someone was able to construe that from my comment.

        That was not a condescending comment by my read. Replace counting in other bases with “theoretical physics” or “woodworking” and it doesn’t read that way either. I think this xkcd is relevant here: https://xkcd.com/2501/ https://xkcd.com/2501/

        I was taught how to count in binary in grade 5, is this not a normal thing that kids learn in school?

      I’m fairly certain I was taught the unary counting system in either kindergarten or 1st grade. And I wasn’t even in an advanced course.

        I think that's noary math instead of unary. or maybe nonary/nunary(can only count women in habits)/zipary/nilary/???

  I was taught binary math in elementary school in the mid 70s. The problem was that they had to teach it to the parents too, unless the parents were not able to help their children with homework.

    It’s a shame we limit things that way, keeping kids from learning more than their parents.
