Basic Number Properties for Algebra 

Professor Dave Explains

Before we dive into solving all kinds of equations, we want to just quickly go over some number properties and how they will apply to algebraic expressions just like they did for arithmetic ones. Most of these will be familiar, like the commutative and associative properties, as well as the distributive property, but they will become even more important in algebra. We also go over a few other basic ones that are completely intuitive, but still worth mentioning. Take a look!

Whenever I’ve tutored college students having problems with math, it has ALWAYS been the case that they never understood the properties of numbers. I blame their high school teachers.

i blame myself. if my high school teachers were simply inadequate then the whole class would have failed. sometimes the students just dont try hard enough, which was the case with me.
@ThoughtfulFusion
@ThoughtfulFusion Месяц назад
@@adamakii That may be true, but there is also the factor that they do not teach the proper knowledge in high school. Students have to go and find it themselves outside of high school, and whilst it may seem they are trying harder, it should not be this way. They should not have to search for the answer, school should give it to them. That should be the point of education. We should learn what we need to know in school.

Actually no. you understand this completely you just don't think you do because he might be explaining it in a way that is different from your way of understanding it. most people like to think shit of themselves for the sake of being edgy or for the "lol im so dumb lol" or to make people feel sorry for them and use that as an excuse to be lazy and not do anything for themselves. they dig themselves a hole that they created. its no one else but you. Note: just because you don't find something useful for yourself does not mean its not useful at all. If you stop and breath and think, thinks will come together for you. Not just math and science but in life. If you stop, breath, think, and just breath, you would be surprised what can do and what you are capable of in life. stop and reflect sometime. most people just don't want to acknowledge it because people are afraid to look like some "nerd" and "know-it-all" :/ Fuck what people think and stop and breath and think. instant gratification is fucking this world over. no wonder there are so many karens and people that think that 5g causes covid. because no one stops to breath and think. Dont think little of yourself. Be the change you want to see in the world.

a Landmark. Nothing gets easier but this is what makes it so fun and engaging, mathematics is indeed a fascinating subject. I've always detested Math ever since I was child, mostly due to the fact that my teachers used to present it in a way of following something, they want you to memorize formulas instead of actually understanding how the basics work. And that type of learning stumped my growth. I prefer mastering the basics first before moving on in much more advanced topics. If I'm unable to, then I wouldn't understand anything they teach me. Much thanks for this Professor Dave. You might not see this because you must be out there stomping on flat earthers right now

Small correction at 4:28 min: x*(1/x) = 1 is only true for x not equal to zero. ... it may sometimes lead to problems. ... Having said this, I would like to underline that I love your videos, they are very clear, brief and give just the right amount of information! Thanks.
