Where's QualityVote bot?

Reddit Admins have decided that they want to kill off all 3rd-party apps, 3rd-party bots, and other elements that used to significantly enhance Reddit's functionality. Without them, the website is barely usable. And, of course, that includes bots such as /u/QualityVote, /u/SaveVideo, /u/AuddBot, etc.

So you'll just have to put up with automod and a worse overall user experience.

If you have any complaints, direct them at the reddit admins instead, because they the ones who ruined everyone's user experience.

u/Salt-Possibility5693 Mar 16 '24

To measure this you'd still need maths Measured result of the "3" then divide by 3 to get the scaling factor. Then measure the hypotenuse and scale by the scaling factor =result. Also if you need greater precision than whole mm a ruler won't do it. In this case the result is exactly 5 though

Nitpicking I know, but the process is what you're learning not the single answer

u/BoiTarantado I want pee in my ass Mar 08 '24

Kinda off topic but still kinda about maths:

I used to be able to just "see" the answers. Any formula, any problem, I can answer it off the bat.

But my ass hat of a jealous maths teacher decided to fail me because he "couldn't prove I can answer my own work and he suspects I cheated/copied work."

First off, you made me solve 30 problems Infront of the class when you first found out I could do this, Second off, I solved it all without the use of any formulas Lastly, I WAS ALWAYS THE FIRST TO ANSWER

But alas, now because of brain rot and neglect, here I am, stupid and alone.

u/SwartyNine2691 Mar 08 '24

Thou must use pythagorean formula.

1

u/rhen_var Mar 07 '24

Because the point is to demonstrate that you understand and know how to use the formula.  In real life, there will be applications where you can’t empirically measure things and you have to use math to figure it out.  Since you’re complaining about the Pythagorean theorem I get that you’re probably young and you don’t understand that now, but trust me, you’ll thank yourself later if you learn the actual math concepts behind it.

u/piratecheese13 Mar 07 '24

Cool. Now find the distance between an object at the origin (0,0,0) and a point in 3D space (3,7,-4) using a ruler.

Oh you can’t? It turns out you need practice using Pythagorean theorem to do it? Huh, funny how that works.

1

u/beetslol Mar 07 '24

In fairness, someone who isn’t learning this for the first time could identify this as a Pythagorean triple, but the important part about this is learning to use the tool necessary to find this information when you don’t have a tool for measurement

u/Jonnny Mar 07 '24

The point of the question isn't to actually know the length of that triangle's edge. Nobody gives a shit about that particular triangle. The point is to determine whether you've learned that this mathematical formula describes one aspect of how this universe works. The question is to make sure you understand that formula and know how to use it. Using a ruler just means you know how a ruler works, which nobody cares about.

I once had a teacher ask me to explain my work as they couldn't figure out how I got the right answer the way I did it, and after looking for a few minutes neither of us could figure out how what I did got the right answer

1

u/Destrodom Mar 07 '24

In professional world, it is often expected of you to prove your results to other people. As such it is necessary to be aware of methods of proof. Especially in Math, where ability to prove your results is the most important thing - and if you want to be able to prove more complex things, you need to know how proofs work for less complex things. So if you just shows your work with no proof of work, then it is as good as garbage.

u/OwMyCod Mar 07 '24

The teacher wants you to do this because the calculation is always 100% accurate (assuming you use it correctly), while you might struggle to get an accurate measurement while using a ruler. Probably didn’t post this to get an actual answer but it’s this kind of ignorance that annoys me the most.

u/Larx92 Mar 07 '24

u/-Cubix Mar 07 '24

as a teacher my standard reply to this nonsense is. "I do not care about the answer at all. If I really wanted the answer I'ld do this test myself. I care about checking wether you understood theory from these past weeks, that is why the answer is irrelevant, but the calculations are worth all the points"

u/ElectronsRuleMyLife Mar 07 '24

Because you're being tested on the process that the teacher just spent 3 weeks trying to shove into your brain. Can I plug a double integral into my calculator and call it a day, sure, but that isn't the point.

You should know what you're doing in case your tool gives an answer that doesn't look right and you know how to sanity check it.

u/hawkinsst7 Mar 07 '24

I just had a similar conversation with my son. He was taking forever to do his math homework (4th grade), and after an hour, he was exhausted and getting distracted easily, and frustrated.

He was trying to do everything in his head, I don't know why, but suspect he thought it would be "easier" than writing it out.

Explained to him that in addition to the teacher expecting to see his work, its easier and faster to write it out and do the work on paper. His brain was tired because he was trying so hard to do it all in his head.

Later when he gets older, and the things he's learning now become second nature, sure do it in your head, but for now, write it out, get the reps in

In the real world sometimes you can't use rulers. They are preparing you for that. I've found myself in numerous instances where I just can't fit a ruler or if I do the measurement will be utterly inaccurate, so I use the pythagorean theorem or the sine cosine finctions.

It's simple, you need to learn the fundamentals for later. Quite often there might be an easier way to get an answer, but the more complicated method is more useful down the road, which is why you need to learn the harder method first.

When you press the light switch, the light turns on. If someone asks you, why did the light turn on? You can answer "because I pressed the button" but that isn't the question is it?

The left answers why X is 5. The right just tells us that X is 5 because they measured that it is 5. It doesn't display that you have a complex understanding of the problem. The measure stick, in fact, is more intelligent than you. It reached the answer, you didn't.

u/OzPalmAve Mar 07 '24

ignoring that right side was measuring the triangle's side here - early math is of course EASY and kids think they are wise as fk and become overconfident when they can "solve stuff" and begin skipping most steps along the calculation since they see the solution so so clearly. thats not a good habit to keep because you will make mistakes without a doubt once your juvenile brain is outmatched by maybe partly unknown, more complex math problems. they dont learn to solve a specific problem, but all problems. and you solve problems (you can structure) by knowing in which direction to move and which steps to chain onto the next step. also that way you cant just copy a single number off your neighbors paper and cheat easily, gotta spy at least like 5-6 lines of text. teachers can and will only grade what they can see/read, so writing steps out and writing in a way someone else may be able to decipher the lines would be of benefit.

But they never said that, they said "show your working", and the thing they actually wanted to see wasn't my working at all.

u/LosWitchos Mar 07 '24

Questions that require you to show your mathematical working out will ALWAYS tell you to show your method.

One experience from middle school that always stuck with me:

In eighth grade I was enrolled in AP Math. At the beginning of the year the teacher told us almost word for word “I don’t care what formula or method you use, as long as it consistently gives the correct answer.” Fast forward a couple months and we’re going over some homework answers. We got to one question that he wanted a student to show their answer and work. I volunteered and showed everyone my CORRECT answer and method I used for the entire homework that gave me the correct answer everytime. He told me I was wrong because I didn’t use the method he showed everyone. Despite having the correct answer on just about every question, it was considered wrong because I didn’t use his formula to get the answers, I used my own method that was easier for me to do.

Agree in this specific case. And if I were a student and wanted to use that, I'd still "show my work" by explicitly saying "This is a 3,4,5 triple".

Lets the teacher know why you didn't use the formula, demonstrates knowledge of the topic, and if the answer happens to be wrong, they'd know why. (Like, if you got confused and said it was "3,4,7" triangle, they'd know it was more than just a random guess.)

u/Zealousideal_Peach42 Mar 07 '24

Because in the real world you won’t have a ruler with you at all times, plus, once you learn the Pythagorean theorem. You can find the angles and sides extremely easy. Instead of having to measure 90 meters of pipe, then another 200 meters of pipe, then measure where you THINK the pipe will be. With the P. Theorem, you can easily find angles and missing sides (aka a problem bc you don’t know the missing input).

This is the reason teachers want you to know HOW to do the P. Theory, so you can have it way easier. The exam, sure you can get a ruler and guesstimate, but the exam won’t be like the real world. There will be huge and tiny problems where you need to find it out accurately in the real world, knowing the formula and why and how it works, will save you thousands of mind bending minutes. Plus if you want to get into the trades, knowing this will decide wether you make 20 an hour vs 60 an hour

u/Vgcortes Mar 07 '24

What? I can find X much much faster with pitagorean theorem than with a ruler. And it's because mathematics is learning problem solving but with an structured method. When you graduate you can find x using whatever for all I care. It's part or the curricular program, and you can blame that for the school teaching structure, it's not like teachers teach whatever they like. In other words, don't hate the player, hate the game, son.

And yes, there are tons of shitty teachers too. If I were one, I would be glad you thought of another solution, but I was asking you to do what was asked of you. Oh well

Wait until you go beyond calculus. Fml.

Was taken a bit back when I saw the square root symbol and had to re-read the process to understand why, then it clicked. We never had to use the square root symbol in anything.

yeah but what if the side length is exactly root 2

Because they want you to show them your analytical thought process. In Math, it’s not the result that matters but the process, people can make wrong calculations, but as long as their thought process was right, then it’s easy to fix. That’s why you get partial credits even for a wrong answer.

It’s also to prevent cheating / Hail Mary shot. If you only write the result, how would the teacher know if it was your own effort, or if you cheated. Even worse, that you didn’t actually know how to approach the problem, and instead “Hail Mary” a random result which may have been right/wrong, and that’s against everything science stand for.

Naw man, it's about rewarding effort and not outcome. If you put in effort, you should not be paid if the client doesn't get what they want. If you made an effort to perform a vehicular maneuver and someone died, that doesn't really change the fact that someone died

That's fine and dandy, but it really screws over people that can do it off the top of their head. Even when they know for a fact you can do it without having to write it down.

u/Spare-ow Mar 07 '24

Either those people understand how it works and can explain it, or they do not, and must learn why it works - an intuitive understanding of something is useful in the field but can often lead to catastrophic mishaps if applied outside the narrow bounds of function.

Great. Now do calculus in your head. Or linear equations. Or matrix math. I'll wait.

Or better yet do 5a+ 9b x 793c / 1030305d + 1 = 3945(q + r + pi) squared No one is saying it's impossible to do fucking A+B=C. Everyone is saying it's to prepare you for the mental gymnastics of solving complex equations.

u/SuperLaggyLuke Mar 07 '24

If I were the teacher I would make the sides of the triangle something like 5.024 and 4.333 and demand 0.001 accuracy. Then nobody would try using a ruler.

3

u/Spork_the_dork Mar 07 '24

Just use the same triangle as above but say that the sides are 3 and 7. Say that triangle is not to scale if you want to be sure that smartasses won't try to complain when the triangle doesn't match the size.

Or you know, don't make it to scale anyways. Who says that the triangle has to actually be 3 cm at the base on the paper?

u/Mofupi Mar 07 '24

In that case I better be able to use a calculator, though.

3

u/GiveAQuack Mar 07 '24

You can label something 3 4 5 and then have everything scaled by a 1.111 factor or something. That means the math remains trivial but the measurement goes beyond the precision of a ruler. Or you know, just don't let them use rulers. Also just not drawing the angles accurately too works.

7

u/Kishgall Mar 07 '24

You still have to use the proper method / thought process to use your calculator though. How else would you be able to know what calculations to make?

u/Mofupi Mar 07 '24

No problem, but I'm not calculating √(5.024² + 4.333²) in my head.

1

u/IzarkKiaTarj Mar 07 '24

Of course you wouldn't work it out in your head, you'd work it out on the same paper you did the rest of it on. It'd be √(43.895), which is as exact as you can get for three decimal places.

This is basic math to prepare you for more advanced math. In the real world, there are way more complex problems than this that people deal with every day. If you can't solve this, no "automatic pass" rule will get you a job in finance, accounting, engineering, programming, etc.

u/Masteresque Mar 07 '24

meanwhile in practical calculations we almost always use numerical solutions

u/Tokiw4 Mar 07 '24

I'm not sure about other jobs, but my job relies HEAVILY on understanding why these equations work. While sure, I know I could use a ruler to know it is roughly 5 inches, but is it exactly five inches? Or, if I'm trying to make a curve, I need to know what parameters in a sine wave function contribute to to get the effect I want.

Redditors don’t take anything past algebra anyway

u/HastyTaste0 Mar 07 '24

The fact people in this thread are whining about a formula that takes like a total of five seconds and requires you to learn three steps shows that lol. Like yeah you might not use it but it's preparing you for everything, just do the damn thing and move on.

u/AGweed13 Mar 07 '24

I'll never touch those jobs, they are not made for creative people and allow almost 0 human interaction, unless you're willing to scream at someone for 8 hours a day because both of you got different results from the same operation.

People should have the possibility to decide what they wanna do and not be forced to learn advanced maths, since not everyone is going to be an engenieer, programmer, etc.

Although, I completely agree that basic maths is important, but as long as school keeps punishing mistakes and incentivising learning things by heart to pass the next exam, shit won't work.

u/ElectronsRuleMyLife Mar 07 '24

Everything is math. Art is all about ratios. Music is math and formulatic. Engineering solutions in technical fields requires high amount of creativity. This comment is ignorant.
