How can I improve my calculation skills and speed?

Hi, I was wondering how can I improve, like I said in the question, my calculation skills and speed. For example I was doing my homework and I tried to solve an equation (it wasn’t neither long nor extremely difficult, it had some X some parentheses, etc…) in my head, which took like 3-5 min. But strangely enough, I was at the grocery store a couple of days ago and I had to sum, if I’m not wrong, 1,79+4,95+0,50, and I don’t know why, but I couldn’t calculate that. I kept getting mixed up and couldn't manage to add more than two numbers together. Not to mention division and multiplication—I know how to do them, but they’re often tricky, especially now that I’m learning to figure out the day of the week for a specific date using the Doomsday technique. I’m not saying that I’m not good at math, I have good grades and I can do things like logarithms, draw a function using derivatives, limits, ect… (since that is what I learn this year) but I want to improve my calculations skills (obviously using my head).

Thanks!

How can I improve my deduction skills?

Hi, I joined this community to learn more about deduction and how can I improve my deduction skills. I read some of the comments under some posts and I noticed something interesting: everybody knows a lot! What I mean is, for example, seeing a lot of “deduce based on my bag contents” that you know a lot like physiologically speaking, you know a lot of occupations, and what I thought was that in order to improve my deduction skills I need to learn more about people, animals and the world in general.
What do you think? Do you have any advice for me? If you want you can test me in order to give me more specific advice

How can I become a better strategist?

I don’t mean strategy only in games like chess or RTS games. I’m talking about real-world strategic thinking: creating plans, anticipating other people’s actions, adapting when things go wrong, and solving complex situations.
I’ve noticed something about myself. I’m fairly comfortable with logic, analyzing situations, and deductive reasoning. However, when I have to come up with a strategy from scratch, my mind often goes blank. It’s like I don’t have a framework to build from.
For example, if someone gives me a strategy, I can usually analyze it, find strengths and weaknesses, and even improve parts of it. But if you ask me to create one myself, I struggle to know where to start.
I’m looking for practical ways to develop this skill, not just theory.

Some questions I have are:
Is there a general framework or mental checklist that experienced strategists use?
How do you practice strategic thinking in everyday life?
Are there books, courses, exercises, or hobbies that helped you become a better strategist?
How do you learn to anticipate multiple possibilities instead of thinking in a straight line?
Are there any resources from military strategy, psychology, business, game theory, intelligence, or other fields that are especially useful?

I’m willing to put in the time to practice. I just feel like I’m missing the underlying process that good strategists have, and I’d love to learn how to build it.

Any advice would be greatly appreciated.

Do you have any advice?

Hi everyone, this isn’t my first time using memory palaces, so I know the basics, but every time I use them, after a couple of weeks I stop and I don’t know why, maybe it’s because I get bored or something else.

Anyway, I’m trying to use it again and this time I’ve created a big memory palace divided in different rooms for every topic I’m interested in and I’m working on memorizing cognitive biases. The room I’m using is the psychology room and it has a good amount of loci: a desk with a lamp, some papers, drawers, a couple of chairs, a sofa, a window and some bookshelves.

I’m trying to memorize 99 cognitive biases by placing them in 99 different books on one of the bookshelves. By now I’ve “memorized” 12 biases but the problem is that every time I try to recall them in my head I often forgot one, or I switch them, and I don’t know why exactly.

To give you and example this is what I did. The biases are: survivorship bias, swimmer’s body illusion, clustering illusion, social proof, sunk cost fallacy, reciprocity, confirmation bias, authority bias, contrast effect, availability bias, it’ll get worse before it gets better fallacy and the story bias.

I imagined me entering the psychology room and climbing those ladders used for high bookshelves. Once I climbed it I open a red book and I see the titanic sinking with survivors floating on the water (survivorship bias), the I open a green book with a small man that’s swimming in a pool and comes out muscular (swimmer’s body illusion), then I open a black book from which random stuff and fireworks shoot out (clustering illusion), and so on.

Now, maybe it’s because I tried memorizing these biases like an hour ago, maybe it’s because the mental images aren’t good enough, maybe it’s because I need to do more spaced repetition, maybe it’s because of something else, I don’t know, but I keep forgetting some biases, like the social proof, and the availability bias and I need your help to understand why and what can I do to get rid of this problem.

Thank you.
