Just wait until you leave high school and start doing real math. The stuff we are given has easy work arounds because they are not difficult problems. Good luck using “your way” in any higher math course.
That’s because the teachers job is to teach you the technique. If you solve the problem a different way, then you haven’t practiced the technique they attempted to show you
Yo if you guys are in algebra just use nSolve in your calculator, what you do is press menu then 3 and then 1. Type your equation and change the variable to just one letter (I use x) then after you finish typing it out, put a comma and the letter you used in the equation and boom, its solved.
Hah yeah, not using the formula will work 1/10,000 times, so it’s still of concern. Regardless, those chances dwindle down even further when you get to higher math classes, so yes- it might as well be wrong because you’ll likely get it wrong next time. Critical/logical thinking.
If you don’t remember the formulas and laws/rules, you’ll have a bad base to begin learning advanced math, and they only do this for children further driving home that everyone on here is a 13 year old
I got the highest score in the class and I showed little to no work and got suspended for it since I didn't show my work... I got the highest fuckin grade and I went into nationals later but my 4th grade right of a teacher decided to fail me cause of the lack of work shown
I hate those kinds of teacher. If I got the answer who cares how I did it, clearly I understand how it works. And don't try to pull that "if you don't show the work, that means you guessed and got lucky." I must be the luckiest mother fucker in the world if I correctly "guessed" your whole damn quiz
I learned an easier method of long multiplication in my elementary school enrichment class. Every single math teacher I’ve had since then thought it was some kind of witchcraft
Coming core was an attempt to remove that ideal. They want kids to think analytically. That’s why multiplication is broken down into that ridiculous table; it gives a better visual of the process at hand and how to manipulate it
It’s because the techniques have been proven to work. You need to know how the foundation of how to get from one to the other. Your homemade formulas may not work in all situations
Because shortcuts in math are very powerful, but also very dangerous. What do you do when your shortcut gives you an answer that doesn't make sense and you don't know the right way to do it?
Well that’s the thing about tests you shouldn’t get credit for a right answer you should get credit for showing you understand the material, hence why you get deducted points when you just pull a number out of your ass.
It’s almost as if you’ll apply the same method to much harder problems later so they make you do it on the easy question so that you’ll find it easier later
The reason they teach it that way is because those methods are proved to work in ALL cases. They were derived by some crazy smart dudes and as you get more advanced, you need those foundations to build off of
I had a teacher who gave half points if you were still right but always explained that learning the formulas and being able to solve the problem that way is also important because the way you may have created to solve it may not solve every variation of that problem, causing a struggles later on.
Anyone that thinks their way is better is horribly mistaken. Trust me countless mathematicians have done ur way b4 and they have realized that the way the teacher teaches is much more efficient
Learning the process and proper technique is good. U won't believe how many high school graduate know in college still taking high school algebra cuz they don't know what they're doing
My AP Calc teacher, when we first learned something, would make us do it the way she taught so that way we'd know what each thing meant and then, once she taught us the other ways to do something, she'd let us solve it whatever way worked best for us
Teachers want to show you multiple ways around solving a problem. Sometimes you won’t have a calculator so you’ll have to do the math the long way. Sometimes your shortcut won’t lead you to the right answer.
If you dont understand early on you must use formulas you will plateau and stop progressing at a certain point. (Higher algebra/ calc) you need to use formulas. Take the advice from someone who had to learn the hard way
My teacher took points off for me adding a negative (you know when you have a negative in an equation and it’s like 5 - -5 so you make it 5 + 5?) and I got hurt so badly on so many tests because that’s how we were taught to do it our whole lives then this cuck comes along
I hated that shit in high school they’d make you show all work for test when you could literally figure the problem out in two steps instead you had write the whole 40 steps it took to get the answer
Formulas are good because they are created to be built upon by other formulas. You might be able to do basic algebra without using the “proper equations” but once you get to calculus, good luck trying to make sense of what is going on if you don’t listen to the equations the teacher gives
Well math has stepping Stones, there's methods that grow beyond and eventually "but I got the right answer" might not work with other similar equations
Yes you solved it differently but they teach a certain way for problems that can ONLY be solved using that method you decided to skip. Then you complain how they don’t teach you anything when you do have to use that formula you skipped. Congrats tard
My teacher told us how to do every question using only the graphing calculator saying it was better to lose points than to get the whole question wrong. Now I have to re-teach myself everything for a math placement test that I can’t use a graphing calculator for.
I had a greater understanding for calculus and algebra when I was in my private Christian school than when I switched over to a early college high school. Common core is a joke.
I'm honestly grateful I didn't have to learn this common core bullshit. My niece spent a good 10min explaining how to figure out there's 120mins in 2 hrs. Whn I said she could also just add 60+60 "that's not how ur supposed to do it"
Taking math in school isn't about getting the correct answer, it's about the process you used to get their. The teacher doesn't care that you got the right answer, they care that you used the correct logical steps to get their so you can repeat the process in the future.
This shit pissed me off got the longest time until i got into really high math classes and realized they wanted you to know the technique for very difficult problems, the answers don't matter at that point
I’ve been using nothing but a calculator since 6th grade and now I’m in college and can’t do mental math. But that’s okay because we always have access to calculators
I don’t think I’ve used a single method a math teacher had ever taught me since I was in 2nd grade. Tbh typing that I’m tempted to become a math teacher and tell all my students “do whatever you want”
I personally think kids that are observed to be skilled in math should be taught the concept of what is happening, like what a derivative is, and then let them work for a bit to try to develop own methods that work, then after teach the main methods and rules to improve their own ideas
Formulas are encouraged because they have been proven to be right 100% of the time (with some exceptions) if you use it correctly. Teacher probably just wants to make sure you learn a way that is for the most part proven to be correct.
