What is some practical math that can help you in everyday life?

 >> Anonymous Sun Aug 7 03:34:25 2022 No.14736119 People don't use higher math irl because their brains have been trained by society to believe it's not necessary. But it can be. For example the other day I had to decide if I wanted to do something or not, so I ran a risk analysis with some estimated probabilities and outcomes. Turns out I has a +90% of success, and I was letting a very unlikely outcome distract me from the fact that when all the possible outcomes had been accounted for, it wasn't nearly as bad. I did what the risk analysis told me to do, and it was a success. Integrals aren't used by people in real life, because people have been conditioned to believe you don't use integrals in real life. But the more I try to break the conditioning the more I realize that if I look for chances to use them, i probably will.

One thing is knowing HOW those things work, that's important. Understanding the concepts and what they represent. But if I want to integrate something, I just do it numerically with the computer.

 >> Anonymous Sun Aug 7 20:07:29 2022 No.14737903 Simple addition is pretty useful. I use addition pretty often in my daily life. For example, sometimes I have one of something, but then I get another one, and I need to figure out how many I have now.

 >> Anonymous Mon Aug 8 01:09:10 2022 No.14738446 >>14732864I do equity research and it's pretty darn difficult to get right.Firstly you need to be able to correctly make calculations from the reports, the calculations themselves aren't difficult (just basic addition and multiplication), but figuring what values and measurements to be included for a company to make for meaningful comparisons to competitors in the same market gets incredibly complex quickly.You have to know how to filter out what is relevant and what is not. Then it becomes a question of information, you have to be updated and know how literally ANY piece of information will affect your industries/stocks. This requires you to constantly be checking the news and being ready for taking opportunities or avoiding loses (and of course have a broad understanding of the world and it's resources).Thirdly it is a question of time, you have to do all this in a timely manner for it to be worthwhile. As an average person it is just not possible. You don't have enough capital to truly make enough for it to be worth your time.And then finally, let's say you have done all of the above. You analyze an entire industry and find a company that you truly believe in, and think is undervalued and buy the shit out of. Everything you have done might still be correct, and the stock will go down for some reason, and never recover to its intrinsic price. You need to be extremely confident in your abilities, but also know when to cut your loses.tldr: unless you truly enjoy it, stock analysis isn't worth your time. If you enjoy it and are good at it, just go work as an analyst.
