Hey @foo_fighter. Hope you had a good Xmas/New Year. Looks like the #dotNet and #dotNetMAUI bots both broke on the 28th of December. Could you take a look when you get a chance please? 🙂

7/7

So 3+1/2+6 in the OLD way meant (3+1)/(2+6)=4/8=½, but NOW means 3+(1/2)+6=9½! And the result of people not knowing the difference between an expression and a term is you end up with Youtubes and blogs who think ab=axb, NOT (axb), and that only the first NUMBER/PRONUMERAL is in the denominator of 1/ab, so THEY think it's 1/axb=b/a, NOT 1/(axb), even though just looking at Maths textbooks can quickly debunk that... but they never looked in any Maths textbooks! I call them the #disinformati 🙂

And one of the big issues there is some people - even some textbooks(!) - calling a Term "an Expression", but then ALSO calling an Expression "an Expression"! This is relevant to the pre-20th Century definition of Division, which was everything (the EXPRESSION) to the left divided by everything (the EXPRESSION) to the right, but then, sometime before the late 19th Century, it was changed to the TERM to the left divided by the TERM to the right....

Lastly, Expressions. Expressions are made up of operators and operands (Terms/Products/Monomials). So, 1÷2 is an expression, 1 divided by 2, whereas ½ is a single term, grouped by a vinculum. In a single line we can represent the latter by putting it in brackets, (1÷2). It's important to understand that a Pronumeral CANNOT CONTAIN AN OPERATOR, UNLESS it's in Brackets, otherwise that would make it an Expression, NOT a Term. So 1÷2(b+c)=1÷(2b+2c), whereas (1÷2)(b+c)=(½b+½c)...

But in the context of collecting like terms we have ALREADY DONE ALL MULTIPLIES AND DIVIDES, hence they're not mentioned in those chapters. Some people then incorrectly read between the lines here that Terms AREN'T separated by multiply and divide, but we have already seen a definition which doesn't even mention signs at all(!), as per several textbooks. Terms are separated by ANY operators. We can see then that 3(x-y) is a SINGLE TERM, as the only operator is INSIDE BRACKETS...

3/7

The most concise definition I've seen of "Term" is separated by operators (plus, minus, multiply, divide) and joined by grouping symbols (brackets, vinculum, exponents). I mention this because sometimes there's a context-specific definition, like in a "Collecting like terms" chapter, which only mentions plus and minus, and some people incorrectly read between the lines that they AREN'T separated by multiply and divide...

Next is Terms/Products, though in different contexts may also be referred to as Monomials or Operands. Terms are made-up of one or more pronumerals and/or a number. A Product is THE RESULT of a multiplication. If a=2 and b=3, then axb=ab, 2x3=6, axb=2x3, ab=6, though sometimes textbooks will show you the intermediate step(s) of working out, ab=(2)(3)=(2x3)=6, the important thing here is that a Term/Product is a SINGLE NUMBER, so there needs to be brackets in any working-out steps...

[#]MathsMonday #Maths #Math

I want to discuss some #Mathematics terminology, as I've seen some people tripping up on it, particularly around what an "Expression" is, which I'll get to shortly...

First up, Pronumeral, but also commonly called "Variable", though strictly speaking that's not true, since sometimes Pronumerals are constants, like in a linear equation, y=mx+b, where "m" (gradient) and "b" (y-intercept) are both constants. In this case "pro" means "substituted for"...

[#]TechTuesday

This #Lemmy post https://programming.dev/post/22672085 links to the recording of the talk I gave earlier in the year, about how #dotNet #dotNetMAUI and other #programmers #developers can get the most out of #Mastodon and the #Fediverse in general. Show to people you want to come here, or watch yourself if you feel like you could learn more about it.

I just posted this https://bsky.app/profile/smartmanapps.bsky.social/post/3lckhlmvzbc2r on #bluesky. If you are or know of a #DotNet account who mainly/only posts over there, then please let me know the #bridgy address and I can add that to my dotNet starter thread here. This is still my main posting place - no need to follow me there too - I'm just looking to add more people into my feed who mainly/only post over there (and also provide that same info to others who want to do the same).

A lot of my followers are already #programmers, but for those who aren't, that might be interested in #learning to #program, here is a Github repo which lists a whole bunch of #free #resources for learning #programming, in multiple languages!

New milestone, thanks to all my followers, especially since I'm mostly a booster still - I'm looking forward to quote-posts in the next Mastodon release! With that feature I'll be adding more of my own thoughts. Technically I could copy the link, then make a new post and include the link, but the preview feature is a bit iffy (so needs a screenshot too), and more work than just pressing boost 😉 So onward and upward to 500, with more Tech/MAU posts, education/Maths posts, and a few odds and ends

[#]TechTuesday

ICYMI did you know that you can use your #mouse #ScrollWheel to #scroll horizontally? All you have to do is hold down the shift-key at the same time. I saw (and boosted) a post about this recently, and it's life-changing - so much easier than trying to grab the thin and almost invisible scroll-bar! (thanks Microsoft for making everything harder to use due to your never-ending commitment to giving us changes we didn't want)

Where CAN you get reliable information, or know people can easily fact-check it if not? The #fediverse of course! 🙂 Not the ONLY reliable source of info, but I wanted to highlight just how difficult it can be to get reliable info on privately-owned sites, and to be aware of these issues if you are on such a site. The extreme limitations on comments on Youtube caught me unawares for example. It goes well beyond just censoring out bad language.

5/6

Person running the site says it's because the comments can became toxic, but guess what? Didn't allow my comment to be posted, even though it was all business! The "moderation" excuse is being used to censor opposing evidence. @dm319 posted a comment there, and it got through, but he didn't cite any textbooks. I did and had my comment "moderated" into oblivion. This person "hasn't seen any textbooks" because comments which mention them get deleted!

So...
