Grand Rapids Battle Ball what made you decide to do this?

Not at all really

Every sentence ending with a raised tone. God save us all

Haha this comment is underrated

Go ahead, hack my webcam. You'll just see me ranting to empty rooms and helicoptering my dick around just in case anyone is watching.

lol I try

My feelings exactly And i'm a self taugh hacker Yet there are people that can reverse engineer firmware for shits and giggles

That’s basically you saying: “Hey robber, take my stuff. You deserve it because you tried so hard to break into my house.” Hahahaha

I would say post middle school

@@lkjsdf9544 yeah i think middle schoolers could probably understand this, which is really good for kids who wanna pick high school courses, leading to uni

This is good for me who’s just about to start a degree in computing

@@gumjuicee6746 Hope it's going good for you so far! I also am a couple months away from (hopefully) starting an online comp class

Its a very boring video without any logical start or end..its like some1 talk himself alone n suffer mental illness... its total waste of time..it does not seem natural human voice, but rather computer generated voices. Poor presentation.

I am doing it right now it’s it’s stupid. Probably will to to take desecrate smith again to get good enough grade

I'm tracking u down with my new found hacking powers after completing CS if this shit turns out to be hard Kidding 😈

@@delacruzdaniel7803 when are u going to start?

😊😊😊

Thanks you, I’m scared shitless that I’ll suck at this so thank you for that 😅

lol

Yayy!!😀

Aaron Gould it’s easy

Quadratic formula is overrated

@@ashutoshsamantaray2572 True. Also, there is a better way to "solve for an unknown x" using logic and without guesswork or the quadratic formula.

So true ,it’s really helpful to make the right decision and not just go for it because of the money

says the man named buttery skater

Have you taken discrete math yet? That's where you should learn most of this. Hard but very interesting class - basically learning the math behind all those brain-teaser puzzles you did as a kid.

@@chell272 this is what the video should have stated rather than leaving it to the audience to hash it out in the comments section.

same

@@chell272 should I study aljebra 2 to study discrete math and f so what should I also stud before going to discrete math please tell me

That's what I was thinking . . . Lol. But they cant shake the hands of the same person twice I think was the idea. Idk, I'm tired.

Yeah I think something was missing in the setup to that problem.

It doesn't work because if everyone tries to shake exactly 9 hands, remember that both people have now shaken another hand. This means that if everyone tries this, some people will have more than 9 hands shaken.

thats the worst example wtf. imagine your name is Mike and there are 26 other people in the same room as you. you can shake hands with 9 people absolutely no problem. now imagine you are someone else from that 26 people, let's say your name is Annie for example - yes you can shake hands with 9 people.. and so on. his math problem is missing some words wtf now it makes 0 sense and it sounds stupid. its just like "you are in a pool and you get out of it are you wet" and he forgot to say the the pool was empty on water...

It shouldve been "exactly 9"

Hey, I wasn't the only person who required physics to earn a CS degree. I think that must be a major difference between a quality CS course and a bad one. The bad thing about people who take bad courses at schools is that they cannot grasp why physics would be needed in CS. It just blows my mind how many people do not realize the amount of things a programmer does with physics. There are literally people on here arguing against physics, simply because their course didn't require it. Not knowing physics might work if all I did was create BSTs all day. LOLZ! Let's see, without physics we don't have video games, any simulators period, conversions in temperatures, or equations for motion. We couldn't handle coupled systems, momentum and collision simulations, or simulate friction.

@@mechinizer6911 Yeah, need those jiggle physics for "large chests"

@@plaguedpixel39 Yes sir. We all have to be aware of how the weight of the "treasure" causes outward pressure on containment devices and how the mass will affect the gravitational pull of eyeballs.

Anthony Reese from a theoretical stand point, yeah there's more than discrete math and number theory. you need that fundamental logical reasoning used in discrete math / number theory regardless of what you do, which is why any half-decent CS curriculum includes those two. However, There are many other fields in CS that use other math, but are by no means necessary to succeed in every programming career. Linear Algebra & Vectors for AI/algorithm design/graphical transformation/crypto, Stats for data science, physics in modeling/simulations, and so on. I agree it's better to take most of those courses due to their wide ranging applications, but ultimately there's plenty of programming jobs you can take without touching any more than intro high school math. It's more to expand your horizons and understand the theory and design instead of just using it. For example, I haven't learned much college physics (only through AP); could I use my trig and algebra knowledge to implement basic simulations of gravity, momentum, current, by applying the equations I learned? Sure. But could I be the person that takes the constraints of the problem and derives an applicable equation? Probably not without a lot of research and self-teaching

​@@Darticus42 you're getting into different fields of computer science. In a CS degree they teach the basics, we're not specializing in anyone of the examples you stated. Those are your own choice of what you want to pursue. I was just stating the math needed, because this video beats around the bush too much in order to get to 14 minutes with multiple ads. You want to see the math needed? Easy,just go to the comment section and read what I wrote in 10 seconds.

Hey how r u? Did you get a job by studying math? I'm thinking of it but dunno if it will be easy to find a job thanks

Thank you for the elaboration

@@technicalmaster-mind Keep in mind that different schools have different requirements. Some schools focus on programming aspects of computer science more than physical or mathematical aspects and don't require linear algebra, and certainly dont require calc 3 lol. Discrete math is pretty much universal though.

You missing the point of the vid. Its not about the sheer math knowledge like you would learn in class. Its about mathematical reasoning and how you can apply it to diverse problems.

Hey! I will be starting my Bachelor's of Technology in Computer Science Engineering this fall. I want to do software development and Web Development in the future. What kind of topics do I need to study other than Comouter Science fundamentals?

You don't need none of that shit in the actual tech field if you get your CS degree lmao. Just know some basic math and you good to go.

Yeah but this video was about the math a CS major needs. I run into these types of problems all the time in my classes. I don't know if I will use my knowledge of graph theory in the real world, but I know that anyone in CS undergrad will have to be good at solving these types of problems

Programming and computer science are two different things. Yes, computer scientists know how to program, but not everyone that can program understands computer science. I won't make any assumptions as to your degree, but as Connor Hulla said, these topics are very relevent to most computer science curriculums.

@T3KKANッ You do. The fact that you don't know does not mean nobody needs. It's a wishful thinking of undereducated creatures. Programming is Math, very complex Math, you like it or not.

@@videogamechannels360 Computers can do nothing unless you tell them how to.

@Ayushi Sinha If you look for easier things already, in grade 12, vs. things which are interesting and engaging then even physics would be too complex to you.

Really? I feel like discrete mathematics was one of the easiest courses and I wasn't even that good at math.

Which kind of number theory? Just curious. Btw, I know what NT is, just asking what type of number theoretic problems you enjoy.

@@rishabhdhiman9422 numerical methods, jus a way to compute mathematical solutions (like derivatives, integration and differential equations) by approximations, doing so with iteration method done by a computer in a short amount of time, this theory was built in sweet and tears and it's what is built our calculators and physics applications. It's by no means easy to see the big frame of such dilemma

Same lol, I wanna be an aerospace engineer

YOU MEAN COUNTER STRIKE MAJOR??? HAHAHA

how's it going? im pursuing comsci but i rarely achieve A's in math.

Electrical Engineers were the ones who built computers, so it is obvious they know a lot about the nature of software, because they understand computer down to the physics of electrons. And Electrical Engineering is basically mathematics, it is one of the most math intensive Engineering discipline. You can be sure most proficient Electrical Engineers are also very good mathematicians.

@@BangMaster96 That's just bs.

Can u share the key

Videolicious World started my first week in CS

Wish you Good Luck

@@zenchiassassin283 How did your semester go??

Vaprin “All you have to do is prove that you can’t swap seven and eight by sliding them around.” How is that helpful? That’s the same as proving you can get them back from a swapped position. It’s the same exact problem, and your comment is pointless.

Yea but the problem is if you swap two numbers then jumbled it, how can you know if there are any swapped numbers?

Zero Anims did you watch the video? Only even permutations are possible. That's how.

how did it go how hard is discrete math

@@AllThatRemainsTDH Just took it last semester. Defiantly a challenging course but I passed!

Sooo basically nothing? Jkjk

@@pumpernickelstickybottoms5081 thats because when people say theyre bad at math, what theyre really saying is theyre bad at computations (which is what is taught in high school), which is like a new language one can practice, but math is about insight, you just need the computation to prove your insight is correct.

@@missionpupa Agreed.

@@pumpernickelstickybottoms5081 exactly thats why iq bs is nutjob to begin with we do not even understand intelligence and to add more anyone who sucks at maths usually is poor at its basica or doesn't know basic terms thats all i believe we need to shift our math from literary to visuals to jts rightful form

@@missionpupa I'm actually the opposite weirdly enough. I'm pretty good with calculations (I always got perfect grades in calculus), but I suck when it comes to the creative/intuitive side of math like proofs. I struggle with problems where I have to find a solution without someone giving me a formula, like the one in the video.

What is going on?

I think these sorts of things aren't suited to solving in class environments, much better as homework for those who are interested.
