I'm adhd and suffering from dyscalculia, I'm doing my very best to fix my unfortunate childhood trauma to math. Today at the age of 22 I feel so bad dodging math classes, because I found out that I love math and with math you can improve all your skills to the next level. I'm relearning math from the very basic and also for mental math I started learning abacus as an alternative, hard to keep numbers in my head without them shuffling around like crazy. Btw I'm also no longer around the toxic people who were around me when I was still in school and so I'll be able to move on soon.
True story. I got better at arithmetic by taking your Calculus courses on Udemy. I had learned to do most arithmetic, often multiple steps, in my head. You have this habit of writing almost every step out. The first few hundred times it was driving me crazy. I'm speaking to the screen, "Dude! Skip all that!" Then it occurred to me that by writing it out you weren't making the simple mistakes I often did. I am now the guy who writes out almost all the steps, it's simple but really helps. And yeah, Gaussian elimination, even more so!
This is a great post. Ian saddened every time I hear a student say, “I known how to do the problem; I just made a silly mistake”. Good teachers will assign equal weights to algorithmic technique and computational accuracy. This is great because a student who makes a “silly mistake “ on three of ten problems of equal value would have an overall score of 85 , assuming those were the only errors on the examination. This is significantly less than a 94 or 97 received from a professor who only takes off a point or two because the mistake is considered trivial. By the way, the algorithm must be correct to earn any points. So not getting to one problem and not knowing how to do another combined with 3 silly mistakes gets an overall score of 65 for a student who knew enough to complete 80% of the problems within the allotted time. The reason given for such apparently harsh grading is twofold. Silly mistakes can kill people and cause severe property damage or loss, it costs a company time and money to discover these sometimes not so apparent mistakes. Again thanks for your candid post.🙏🏿👍🏿
Still a problem with your view because there is a big disconnect between exams and real life problem solving/engineering. So I don’t agree with your reasoning that small mistakes matter in the real world so they should matter on exams. In the real world you better believe I am going to use any and all references I have available as well as software to help with calculations. Triple check, or more, of everything. Test again and again. The whole sit for an hour and take an exam no notes no resources is extremely different from my experiences in engineering at a job. I would not grade as harsh as you suggested.
@@TheoPur , the difference is real life problems can and do kill and maim. By the way, c- students are less likely to bee solving real life problems. A habit of working in a manner that results in more so called silly mistakes is not good.
@@mawavoy if C- students were the result of the grading you recommended (65 for arithmetic mistakes) then barely anyone would be solving real world problems
Yeah arithmetic mistakes suck. We are not made to do computations manually, that’s why computers exist after all. When I grade something, I don’t penalize such mistakes as much. Even I could make them
When my son was in early grades in elementary school, he had a big advantage over his classmates in arithmetic, because I taught him how to cast out nines to check his answer for correctness. His tests consistently came back with a score of 100%. I don't know why schools stopped teaching this. The method gave him immediate feedback as to how he was doing, and to correct one's mistakes, you have to know when you are making them.
Hey just want to say thank you for your videos and enthusiasm. I have been brushing up on math as well as learning new math skills and your book reviews have been a huge help! Your overall positive advice is also priceless.
I quickly learned a little trick I call "completing the five" when I got a job as a cashier and had to make change in a hurry. I came up with it very fast and it has served me well all my life for any addition or subtraction problems that I have to calculate in a hurry. One of the main reasons I got into computers was that I'm good with formulas but the arithmetic trips me up. I realized I could let the machine do the arithmetic. I just needed to deal with the bigger picture.
I'm teaching myself how to use the Japanese abacus. I really like it. When you get very familiar with it you don't actually need to use the physical object because you can imagine you are moving the beads in your mind. One particular cool thing is that if you set the number 34 (for example) then you can easily visualize the complement to 99 (65) without doing anything so all you have to do is to add one (65) and you know the complement to 100. This is useful when you pay 7.34 with 10 dollars for example. You set the number 7.34 and without doing anything else, you can visualize that the complement to 9.99 is 2.65 so you just add one ( 2.66) and that's the money they have to give you back. This particular abacus is named "soroban" and you can find tutorials on youtube.
I really really really recommend "How to calculate quickly" by Henry Sticker. It's a dover book and I think is got it used for $5 on Abebooks. There are 31 pages of answers in the back and I believe it's all of them as well! The book was published in 1945 so the wording is a bit confusing at times, BUT take a breath and read again then it'll all start clicking soon enough. I would recommend checking it out and making a video about it. Either way, Dude, your videos are a massive inspiration and further solidify my resolve to get better at math as a whole. Thanks again
This is what I tell.people when they tell me that I was gifted in Math. I explain to them that I have no special gift for learning math. It comes from multituxes of hours of course work, rigorous study, practice', hard work, and then even more.and more intensive rigorous reading and studying. No special gift. Just a lot of work.
Honestly, I think that "arithmetic" is the only field of math, so to speak, that can be used in everyday life, everything else is rarely or never used.
Back in the old days (1960s and earlier) many small grocery store owners were great at arithmetic. They often had no cash register in the atore and no electronic or.mechanical calculators, no adding machines. As a result they became great at doing the calculations in their heads. And fast too. Some.of them would jot the calculations on the side of the paper bag and that served as your receipt. They werw good at arithmetic calculations because they had to do them all day everyday.
Math Sorcerer Sir, I would say that your advice on arithmetic is hauntingly very very similar to what Edison used to say before he managed to get that lightbulb right. And it is what I needed now, thank you again and again.
This is so true. Working on mathematics is just like working out and being fit, it takes endless repeat workouts aka practice. This the same thing with programming and learning to play an instrument. You have to put in a lot of practice over and extended amount of time consistently
You can do speed arithmetic if you learn the Abacus/Soroban and/or Vedic Mathematics. With that said, you still have to practice. Hopefully you can make future videos on the Abacus/Soroban and Vedic Mathematics.
As a layman it appears as though arithmetic is treated as quite lowly and elementary . Not as deep and respectable as the other branches of math. Why is this?
It would be interesting if you made a video about dyscalculia because arithmetic is about impossible for me. I cannot see numbers in my head and makes mental math about impossible since I can’t even visualize it. And understanding math concepts in general. I just finished my first semester in college and got a 1.2 gpa and am about to get tested for adhd which I think I have. I’ve failed pretty much everything and tutoring just doesn’t help as I forget what I learned just hours ago.
I have ADHD and I find that having accommodations to have extra time on exams for that helps a lot! You can also try to ask to have a basic calculator for exams for dyscalculia as well, to make it more accessible for you.
@@happysloth3208 idk man, having more time wouldn’t help at all, I finish all of my test way before anyone else in math because I don’t know absolutely any of it and I can already have a calculator for the test, it does not help at all. I don’t know any of it. I practically have a 6th grade knowledge of math
@@happysloth3208 college Allegra. Math 1101 which is just highschool Algebra taught in a college setting pretty much. It’s the first math you take if you have no credits and no placement test
Once you mentioned that movie, I became curious, if you or anyone else has seen any other great (can recommend) any math-related movies or 'smart' , enjoyable films?? - Has anyone ever seen Aronofsky's "Pi" (1998) ? I need to watch the one you mentioned, The Man Who Knew Infinity
On that note / question: It wold be cool if you were to create some uploads about reviews for movies like that and how realistic / enjoyable you found them and if there were any insights that you could shine a light on for us learners
Does it worth it to get skilful at basically executing an algorithm by hand instead of letting it for a computer? Does it helps or improve in some way our understand of demonstrations and how to make them? I would like to get answers from all users not just the author of the video. Peace to you all.
For me it's helpful to be able to do it by hand, I think it does give a deeper understanding. But at work for instance, I will almost always use a computer, it's faster. Not everyone even wants the deeper understanding, they just want to pass the course. So the answer likely is that it depends on the person.

I'm in possession of a new "A.I." (for lack of a better term) wearable tech that is based entirely on the type of arithmetic you describe with the yogurt, except it calculates very deeply about a variety of things. The processor is always warm from it. Essentially every decision we make in daily life money/time/attention/nutrition etc can be broken down into arithmetic. The device gathers information through cameras and scanners and offers advice based on a proprietary algorithm, advice which is often counterintuitive but. I've been using it for les than two weeks and already my life is transformed for the better from it.
