Yeah, didn't think that came from any textbook.
Except TI calculators also give the wrong answer when a bracketed term has a coefficient.
Yeah, that's exactly the problem with TI calculators - ignoring the rules of Maths.
but the phone is actually correct
No, it's actually wrong.
8 / 2 * 4
It's 8/(2x4). You can't remove brackets unless there is only 1 term left inside.
I’ve never had anyone tell me operations with the same priority can be done either way, it’s always been left to right
It's left to right within each operator. You can do multiplication first and division next, or the other way around, as long as you do each operator left to right. Having said that, you also can do the whole group of equal precedence operators left to right - because you're still preserving left to right for each of the two operators - so you can do multiplication and division left to right at the same time, because they have equal precedence.
Having said that, it's an actual rule for division, but optional for the rest. The actual rule is you have to preserve left-associativity - i.e. a number is associated with the sign to the left of it - and going left to right is an easy way to do that.
Sharp as well.
Not that anyone knows what RSS is
Actually there was quite a bit of discussion about it not long ago in my feed. I'm following at least one bot which is just boosting from an RSS feed.
Indeed it just so happens that Maho is someone who not only investigated ActivityPub, but made his own implementation of it for his own blog(!), rather than using the Wordpress plug-in (but for the DevBlogs account he just used the Wordpress plug-in). And yes, you need a bot to propagate the content of a non-human account - the posts from the Communities here are propagated out to Mastodon and where-ever via a bot.
But yeah, in this context I was talking about you can now follow the blog from Mastodon or Pixelfed or where-ever - one less separate website to check for my tech news, gets brought straight to my feed :-)
There’s only a bot sharing links. Federated would mean more than a bot, right?
When a new post is made in a Community here, the relevant Community bot sends out a link to the post (see screenshot of post the .NET Community bot sent out about this post) - is this Community federated? Same answer.
It’s a bot account that shares links
In other words, does the exact same thing as the bot for this Community does when a new post is made.
explaining others also helps me understand it better.
There's a saying - if you want to learn something then teach it (even to a rubber duck ;-) ).
Cajori (1928) for starters, plus any old Year 7 Maths textbook, any era (we know from Lennes letter that textbooks were already doing this in 1917).
