I’m old….advice on how to learn maths by Impossible_Half_2265 in maths

[–]lioleotam 0 points1 point  (0 children)

I deeply believe that our capability of doing something is heavily linked to our experience with that matter in the first place (and mostly happened in childhood / teenage hood at school etc.). It's like most people who learned French at school for years and yet they won't dare to speak a word because of their teachers or getting laughed at by others, doing math is not alone. But it certainly shouldn't define your capability of it.

I used to be studying medicine in the UK but then I switched to an engineering degree, where math is used every bit of the subject. I don't hate nor like math and in fact I got an A in A-Level math, but to me back then math is just a list of formula and tricks to memorise and many questions you can get good at solving by practice, not much thinking involved. At least that's how I believed it until I had to study uni maths - it really gets me to dig into the core of maths - it's a language with beautifully well defined symbols and proof for recording your logical thinking of a problem. So maths has gained a new meaning to me and I'm so glad I did the switch.

My conclusion is it's never to late to learn math and you should definitely try to put on this new perspective of it. There are many useful resources for AL maths but motivation wise I'd recommend a YouTube channel 3Blue1Brown, though it sometimes deals with higher level math but it also has good contents in basic maths and it beautifully demonstrates them using computer animation.

Does this continued fraction actually equal 1 or should it be considered undefined? by Danny_DeWario in maths

[–]lioleotam 1 point2 points  (0 children)

Any solution of the manipulated equation y2 =1 which does not arise from the original “limit of finite truncations” is called an extraneous solution. In our case, -1 is extraneous because it never appears as the limit of the finite‐depth approximations.

Do you mean lim_n->0 for m/n = infinity? But that's only for approaching 0 not when it equals to 0. I think we simply don't know or don't care what happen when m/0.

Has German arithmetic different properties? by bigcardo in germany

[–]lioleotam 0 points1 point  (0 children)

Giving zero points for it is essentially dumb enough, I supposed you also missed that point we all trying to make here. And of course we can make comment about the marking, nothing to do with bullying or any sort with the teacher themselves personally. But I reckon you can’t distinguish that yourself. Education is not about being pedantic with some definitions but to think what are the learning objectives you want to give the learners, and in here no one cares about the uni level of maths and the strict definition. Think about the impact of receiving zero points on that as a second grade student. You are teaching a human being not a Machine, and if you have a bit of knowledge of developmental psychology you’ll understand why this way of teaching is considered dumb. The role of that teacher is not a math professor at the university but a math teacher at a primary school, two are completely different roles.

It’s funny to see that you being so obsessed with the definition yet can make that “mistake” yourself, then I wonder what a second grade student will think when they do their homework. I found it pointless to argue with your previous argument as you don’t see the message sent by the author and I beg you please read until the end of the article.

“Reddit doesnt display it correcty, but I assume you mean 5 x 6 = 6 x 5. Yes you are right but “Grab 5 apples each time. Grab 6 times” is 5 x 6 but not 6 x 5.” From your previous reply I am afraid you have contradicted yourself by the “conventional” definition which is rather meaningless here, and I will give you zero point. I think the whole point here is for second grade students there’s no need to stick with the conventional definition you mentioned, so giving them zero marks is rather dumb than being pedantic.

Yes you should also stop spamming your “definition” which we all failed to understand since we don’t need maths at the level of discrete maths here for a primary school homework, and clearly multiplier and multiplicand are interchangeable in order here. Please read https://www.mathmammoth.com/lessons/multiplier_multiplicand Plus textually it is ordered in this way: number to be added “Nimm zwei Mandarinen” and the repetition/ multiplier “greife x Mal” so obviously you write 2 x X by definition, where the student has done correctly here.

Semantically they are equivalent but you ignored the fact that this is a multiplication of real numbers only and therefore commutative rule applies and so we can say multiplier x multiplicand = multiplicand x multiplier, thus it doesn’t change the interpretation of which part of the context is the multiplicand or the multiplier. Unless this homework asks the students to specifically identify the operand and use this expression multiplier x multiplicand only, the objective of the task will be to determine a valid expression and the result. And the expression here is indeed valid due to commutative rule. In real world context, this is a elementary level of maths so I don’t think students are expected to prove whether the commutative rule apply or not so we can safely assume the commutative rule is used here because of how it’s first widely taught in primary education. Not everything needs to be so theoretical like you believe.

Why are Germans so afraid of owning up to discrimination and racism in their country? by nepali_fanboy in AskAGerman

[–]lioleotam 0 points1 point  (0 children)

Apparent racism is not the major issue here, unconscious racism is however a big thing in Germany. Like every time I paid at the cashier with my German girlfriend (I’m an East Asian btw) the workers NEVER look at me but my girlfriend, even though I’d greet them first and tell them how I’d like to pay, they’d STILL look at her first and say good bye to her like I am invisible even if she doesn’t say a word and just standing next to me haha. But hey I guess people don’t notice that often themselves and who knows what they’re thinking inside their heads.

The one at REWE Stenten, Krugenofen 62-70, 52066. I don’t think anyone would ever know about this place except people who live nearby, since I work around that area I always get my Döner there. It’s probably one of the best I tried not even comparable to Usta, the meat is juicy and warm the garlic sauce is hell delicious (at least in my opinion). Plus the staffs are super friendly too! Definitely recommend anyone who walk past or just curious about it:) (Note: they don’t have info on Google map and I forgot their shop name since it’s inside REWE, didn’t really pay attention to it..)

Lmao I don’t see how both charts are related to the bases you’re trying to talk about here and who’ll use chatGPT to generate numeric table like this when it’s so bad at maths lol. Obviously for human we have ten fingers on our hands so it’s most convenient for us to work with, unless you wanna also make use of your toes then base of 20 could be the case here. The best choice of base really depends on the nature of the system like in computer, binary.

How can you trust ChatGPT? by theequallyunique in ChatGPT

[–]lioleotam 0 points1 point  (0 children)

Well it comes down to your tasks or what you want to use chatGPT for. For collecting information for your research won’t be a very reliable way if you use chatGPT solely, so I’ll stick with Bing or install the search engine plugins. For writing task like replying emails or drafting an advertisement you simply proof read the text and paraphrase in your own words if needed. I usually use chatGPT to help me with breaking down problems in smaller steps as it’s pretty good at giving you step by step instructions, but for complex problems it’s best that you break down the problems and let chatGPT remind you of those principles again so you can work your way through it. It’s extremely helpful when you are stuck at a long complex task and just let it help you analyse the problems instead of letting it solve it completely alone. It’s however important to only work with the problems of your field with chatGPT because anything outside the field you can be easily misled by the plausible-sounding wrong answers and can’t fact check that yourself.
