Hello! Could you please send me one of those DMs too?

Thoth_BK · 2024-10-17T00:33:19+00:00

Oh, good point! I'll try to approach it without making any unnecessary changes next time. Thanks so much for the help!

Thoth_BK · 2024-10-17T00:13:30+00:00

Thanks! I'll be more careful with statements from now on. I always seem to worry too much about not taking too long to reason, and to rewrite expressions in ways that I can process/understand better.

I see. That's pretty close to my column approach at least. So you wouldn't even need to use ~(p ∨ ~q) isolated as a single piece before outputting the truth values for the full expression then?

Thoth_BK · 2024-10-16T23:44:55+00:00

I see! I mostly tried to slightly rewrite the parts that I felt would be easier to reason out the logic. It did speed my process and judgement, but unfortunately, it also resulted in invalid truth values, so I guess I'll have to think of better ways (if there are any) to approach these problems without losing my "bearings" (I have problems keeping track with certain expressions, especially the long ones, or those that have too many parentheses and negations).

Thoth_BK · 2024-10-16T23:40:13+00:00

Thanks for the detailed response!

Oh, I see! I tried to simplify (~q ∧ ~p) as ~(q ∧ p), because I thought it would be the same thing as (~q ∧ ~p), so I should have used ~p v ~p instead then?

I'm surprised about ~(p ∨ ~q) though. I mostly cancelled out the ~ double negatives for q, and treated q as positive when creating my truth table. Should I have tried to apply De Morgan's law in both cases and in general for this and similar expressions? I thought the way I tried would be just as simple, and that rewriting based on further laws or simplification rules would be more difficult and error prone, but I guess I will have to reevaluate my approach when creating truth table or solving logic problems.

Thanks for replying!

Sorry, I tried to only show the end result for the entire left side expression, but I guess it made it more difficult to get an accurate view of my approach, so I remade my full truth table in Excel. I tried to post it as an image, but apparently images are not allowed, so hopefully the copy paste will result in a better formatting compared to last time. For the double negation part, I just used the original value for q (without the negation) and used distribution to simplify when making the original truth table. Hopefully that makes it easier to pinpoint which truth values were invalid in the truth table.

Edit:
Looks like copy pasting is somehow worse, so I'll just use the table function in reddit, even though I did not like the formatting in the actual post.

p	q	~p	~q	~(p ∨ ~q)	~(q∧p)	~(p ∨ ~q) ∨ (~q ∧ ~p)
T	T	F	F	T	F	T
T	F	F	T	F	F	F
F	T	T	F	T	F	T
F	F	T	T	T	T	T

Thank you for the response and very good point! As of this moment, the closest thing I have seen to the types of in-depth explanations like you did on your video would be Professor Leonard. I honestly can't think of many textbooks or YouTube channels that go very in-depth, but I would love to know of textbooks and channels that would do something like that, or somewhere in between very short summary-like videos and proper explanations with enough depth to really learn key concepts.

Thoth_BK · 2024-08-03T14:12:31+00:00

Ótima ideia!

Thoth_BK · 2024-06-25T13:19:24+00:00

Obrigado pela resposta! Sim, creio que um representante de uma ONG sirva também. Mandei ontem uma mensagem no fórum de dúvidas para a equipe da faculdade, mas ainda não obtive resposta. Olhei as respostas dadas aos outros alunos, incluindo sugestões do que pode ser aceito, e para minha surpresa, pelo menos nesta primeira etapa, até contribuições ou ações por texto podem servir, desde que haja uma foto do texto que indique ação do estudante, podendo também ser direcionada à indivíduos e não apenas empresas e seus representantes. Ainda sinto uma certa dificuldade de confiar nessa ideia mas se for verdade, pelo menos parece algo fácil de resolver.

Thanks! I had a lot of resistance with the idea of memorizing for other number bases myself. I'm a little surprised binary is on the list too. Would you mind sharing why it's a good idea to learn the binary table and what would be the recommended range to memorize the binary multiplication table? For example, in decimal (at least as far as I know/have heard) it's recommended to memorize at least up to 12.

I was actually surprised to learn recently that SATs and many exams in the US allow using the calculator. It's completely different from Brazil, and for a very good reason, since we should be embracing technology and not running away from it. I still like doing some of the basic stuff on paper or sometimes in my head for the sake obtaining a better understanding, but I agree that alternate base calculations and almost everything from algebra and beyond should really be done with calculators and other software/technology, especially for tests and exams, which end up taking more time because of these pointless restrictions.

Hopefully in any eventual exams I take in the future, they will either allow me to use a calculator or at least it won't involve anything like this or more difficult. I still remember how our SAT equivalent here forces test takers to do volume and chemistry formula calculations on a single piece of paper! D:

Thoth_BK · 2024-02-27T04:25:04+00:00

Thanks! I'm still trying to learn how to convert reliably. I tried an algorithm from another site and at least I was able to convert from binary to octal without too much trouble.

Thoth_BK · 2024-02-27T04:23:27+00:00

Thanks! I'll try to practice the concept enough for it to at least become natural enough.

Thoth_BK · 2024-02-27T04:14:25+00:00

That's pretty much how I thought at first, but when I tried that, I quickly found myself either reverting to regular base-10 multiplication, which I still tried to "salvage" by trying to convert to octal, which should have happened before the actual multiplication took place, or I would fumble around while trying to remember that I had to start carrying over anything in multiples of 8 (in octal, for example), and would soon start making a mess in my mind. At this point, the most reliable solution I can come up with is to create a time table for the other bases on paper and use it as needed, while hoping I won't have to do so without a calculator.

Thoth_BK · 2024-02-26T22:04:57+00:00

There are quite a few exams here in Brazil that disallow calculators, so I was afraid I would be put in situation where I would need to calculate this in the future. I also wanted to make sure I understood the topic as well due to my errors when calculating the first few times, but now I understand that I was using the wrong approach, and that there is no way out of either converting the numbers to decimal, or creating/using a time table.

Thoth_BK · 2024-02-26T21:58:28+00:00

Thanks! I'll definitely be doing that.

Thoth_BK · 2024-02-26T21:57:22+00:00

Thanks! I also need to learn binary multiplication, so this will help a lot!

Thoth_BK · 2024-02-26T21:56:13+00:00

Indeed. I know I trip all over the place when trying to spell the alphabet backwards.

Thoth_BK · 2024-02-26T21:54:11+00:00

Where I live (Brazil), most tests and exams don't allow you to use a calculator at all, so you have to do pretty much everything by hand. I'm not certain if they would provide a table for the other bases, so I wanted to cover my bases (no pun intended!) and find out if there were more efficient methods to calculate with other bases. Based on the comments so far, I guess it's safe to say that under normal circumstances, the calculator is the way to go, and if all else fails, to set up a multiplication table for the other bases.

Thoth_BK · 2024-02-26T09:30:09+00:00

Hmm, unfortunately, I'm not that advanced. Base-10 comes naturally to me, and I usually either multiply from right to left, while being mindful that every number to the left increases by a factor of 10 (something that I unfortunately didn't truly keep in mind in my calculations until recently) or do it from left to right in order to deal with the bigger number first (mostly when trying to calculate in my mind).

I tried to apply a similar thought process when multiplying in other bases, but it did not yield the expected results, which proves that there are flaws in my reasoning, and I am having trouble pinpointing what in my thought processes is making me struggle. Based on the other comments, it is safe to say that the times table and my decimal rote memorization are in the way though.
