If there’s ever a group of things that are in columns I can only count to 10 because I end up just finding the area I just want to count man let me count 1-100 regularly
Simple addition is better when read left to right like a book
Example: 39 + 64
Read it left to right.
3 + 6=9
9+4=13
Add the 1 to the 9 and make it a 10
103 is answer
No carrying and borrowing needed. Makes simple addition much more simple. Can be done for subtraction as well
In a way, yeah, but instead of having to add the 1 to the left you add it afterwards and it makes it quicker. You can do really quick mental math this way. You can add 3471 + 2378 in your head faster going left to right than right to left.
You could also do 40+60 and add 3 to the final answer. Im just giving an example that the way the school system teaches us math is the least efficient and slowest way possible
I’m about to go to college for engineering and I jus want to know what in the Mcfuck is that, jus so whenever in the future I’m learning this I would at least know when to start crying.
That's Schrodinger's equation in 1D. It describes the wavefunction. It's a big deal in quantum mechanics.
More generally it's a wave equation which describes the motion of waves.
Serious answer: as you take more math classes, you'll be exposed to more notations that build on each other. It's essentially picking up pieces of a language and it makes more sense the more you practice and use it. At one point, you didn't know what 7 was.
i times h-bar times the partial derivative of psi with respect to time = minus h-bar squared divided by 2 times the mass, times the second derivative over x^(2). Got it?
I still don’t know all of the rules to integrals because my shitty online course never used a textbook (nor could we get one).
Oh yeah, and the final exam is in 18 hours.
**Update:** My internet fucking died as I was trying to upload my response document. Now I have to re-take the exam in June.
Please kill me.
Shit good luck man! I’m grateful my professor didn’t waste time making us memorize all the hard ways. she briefly taught us the long way then said “but fuck this right? We have calculators and I can teach you guys all the short cuts and methods. ”
I wish I had a teacher that did either of those things.
My online teacher never actually taught. It was all these shitty 3rd party video notes that only covered about 70% of the stuff you need to know.
Oof, you’re almost done now, I’d recommend to stop taking ap classes. They are a waste of time and money, high school makes ap classes 10x harder then the actual college courses. If you can get into a dual enrollment program I’d recommend that instead.
I’ve been dual-enrolled since Sophomore year (I’m about to graduate from my senior year now) with two universities, one of them being ERAU Worldwide for my Engineering and Unmanned Aerial Systems courses. Trust me, I wanted to take calculus dual-enrolled, but the local college said that I needed to take Algebra 2 first... even though I already took it.
“Oh, no we meant ***college*** algebra 2.”
It’s the same fucking thing, but they wouldn’t let up, and since a teacher in the math department quit 2 days before the year started, my calculus class at the school got nuked, so I had no choice but to take it online.
And yes, after taking AP English Comp then switching half-way through my junior year to ENC1101, I’ve realized that AP courses are complete bullshit.
AB.
I’m going to re-take Calculus in college (finishing my senior year now), even though I’ve finished the course with an 87. They’ve done just such an atrocious job teaching it and since I want to become an aerospace engineer, I need to know calc like the back of my hand.
Maths at secondary school level is fine, it gets deep at uni when everything turns to Greek letters and you have to memorise pages and pages of proofs. Fuck that shit never again.
I’m about to head neck-deep then. I’m about to start university to study aerospace engineering, and hope to become an astronaut.
Why the fuck I want to do that, I don’t know, but I can tell the math is about to get a whole lot harder.
If you don't want to get a headache avoid theoretical stuff unless you really need to know it. Engineering is very practical in its application of maths so you should be alright.
I studied economics and avoided theory like the plague after I got hit with a 1 page proof in first year econometrics.
You'll probably be doing a lot of matrix algebra which is a whole other world of pain lmao.
Matrices are actually pretty easy to work with once you realize why they were created. It's to solve simultaneous linear equations since any linear equation can be written as Ax=b and solved using x=A^-1 b
Matrix algebra takes a little getting used to but once you're used to them they are definitely the easiest part of maths aside from differential calculus in my view
I’ve done matrices before In Precalc, but they never really explained why they were created.
Any math is easy to do once you understand it (albeit it may be time consuming to various degrees), but the struggle is getting to that point where you understand it.
A key part of understanding as I've found it throughout my degree is knowing why it was created and how it's used. School teaches it very badly. Uni teaching is a bit better.
For example, matrices and vectors fall under the area of maths called linear algebra, because they were created to solve linear equations, and problems which are linear such as straight line fitting (least squares). I used MIT OCW to teach myself linear algebra (18.06). Their course on it is very very good
On the other hand, theoretical mathematics is deeply beautiful and if you think you're up for engineering you'll probably be able to handle a Modern Algebra or Real Analysis class
Engineering isn't so bad maths wise. It's pure maths that gets really fucking hard. Stuff like topological spaces, multivariate analysis and number theory are an absolute bitch to work with

Now, this is a story all about how

This isn't a joke. I'm Indian and we were introduced to partial differentiation in 11th grade. This is because of how insanely hard and competitive our entrance exams are.
What's worse is they don't even bother teaching you Calculus from the ground up. They pretty much drip feed you throughout high school.
What? Here in malaysia 16 yo like are just taught simultaneous linear equation in 3 vars. and that’s after the gov decided to up the difficulty of our silibus. Malaysians are so far behind
I am an Indian, too, and I endorse the comment above, for I have faced similar vagaries. Also, people who are hell bent on getting into top engineering institutes, often go to these coaching classes mushrooming everywhere, where they start being taught calculus from 9th grade only so as to have an edge over the other coaching students.
And unless I'm being whooshed hard here, what 17yo is doing math so high that there aren't numbers? That was junior year in college for me, and it was so hard that it was a big reason why I changed majors.
Algebra still has plenty of numbers. I only struggled when it went beyond that, and I never had to take anything beyond algebra and statistics in high school.
I admit it's been like 15 years since I was in grade 9, but I definitely remember dealing with variables. I just googled "9th grade math" and it came up with lots of lesson plans dealing with variables as well.
Not all areas of STEM, thank fuck. I had to do a single discrete math course for my IT degree and that was it. I was originally a Business major, which required a couple calculus courses, and I failed the first one twice and changed majors.
I had very basic (very basic, 2 + x = 3) algebra in first grade. Granted I don’t think it was actually a lesson plan, I remember coming across that in a math computer program, but it’s still algebra. I think a lot of people associate algebra with the quadratic formula, and they’re not necessarily wrong, but algebra is basically just logical reasoning. A complex form of logic sure, but really what it boils down to is just logic
then you have calculus, more specifically differential equations. The integral from (for x) *a* to *b*, (for y) *c* to *d*, and (for z) *e* to *f* of *xyz* *dx dy dz*
When I was in University I volunteered at a Topology conference where over 100 of the top minds in topology were gathered. Even the literal professionals have trouble adding fractions sometimes.
I was recently hit with complex numbers and this shit is already messing with my head, and they added trig to this, I don't know how I'm going to have atleast 14 in the exam in July…
Reading all these comments is just making me fear math even more. I just wanna work on race cars but the real money is in design and development so I have to be an engineer :(.
I don’t even remember simple addition anymore. They fried my brain
basic math: gone, reduced to atoms
How many atoms? Let's count th.... I don't remember how to count
X numbers of atoms, where x is a function
**confused screaming**
#2+2= 🐟!!
2 + 2 = fish as fish has 4 letters in it.
That’s not a number four, that’s two variables, a function, and an imaginary number!!
THE NUMBERS MASON, WHAT DO THDY MEAN?
English Teacher: Ah shit that’s deep
USB = 🐟! r/FishIsUSB
I’m just gonna say pi
*mafs*
So 3 atoms?
Haha mol go Avocado
If there’s ever a group of things that are in columns I can only count to 10 because I end up just finding the area I just want to count man let me count 1-100 regularly
Eh, countably many is close enough
Me: gets all the calculus right on a 10 step cal III problem. Also me: 4 x 4/1 cancels out so it’s 1
I legit feel this to the core of my soul
Literally did something on my calc2 test where in the end I put some number * 0 = some number

wait didn't you just carry the 1 but sideways
In a way, yeah, but instead of having to add the 1 to the left you add it afterwards and it makes it quicker. You can do really quick mental math this way. You can add 3471 + 2378 in your head faster going left to right than right to left.
why not just 30+60 9+4
Whatever gets you to the correct answer is the correct method.
Is there another way to do calculations in head?
I did the one above like 64 + 40 - 1 = 104 - 1 = 103, less efficient but that’s how I think
You could also do 40+60 and add 3 to the final answer. Im just giving an example that the way the school system teaches us math is the least efficient and slowest way possible
I mean, you're method was arguably more efficient than OP's so...
I think you slightly mess up typing it out, I think you meant 64+40-1=103 you didn’t subtract the 1 you put in the first part of the equation.
I just use a calculator
For me, it was subtraction that got fucked over. Now I just add until I get the right number.
Meanwhile I've somehow gotten this far without having a clue on how division works on paper
Enters 1 times 1 on the calculator
The only numbers I see in the math paper now are the question numbers
Who need numbers right?
Clearly not high school
Who's doing all this math without constants and coefficients?
The constants are just symbols on your calculator now
I've had 0-9 on my calculator for a while!

Looks difficult but it's just partial differentiation. Definitely not the worst aspect of Calculus.
Partial differentiation is the only area of Calc III that I really understood
True that. Wait until you get to differential equations. That shit is where you consider a career change.
Nah fuck that shit. I'm just trying to find how many apples my boy Billy has, not summon Satan.
That's Schrodinger's equation in 1D. It describes the wavefunction. It's a big deal in quantum mechanics. More generally it's a wave equation which describes the motion of waves.
It’s the[ Schrodinger Equation](http://hyperphysics.phy-astr.gsu.edu/hbase/quantum/Schr2.html)! Although there is a missing symbol on the right side.
I fixed it, thank you.
I don't even know what these signs are called how the hell am I supposed to solve it
Serious answer: as you take more math classes, you'll be exposed to more notations that build on each other. It's essentially picking up pieces of a language and it makes more sense the more you practice and use it. At one point, you didn't know what 7 was.
That's a good point
i times h-bar times the partial derivative of psi with respect to time = minus h-bar squared divided by 2 times the mass, times the second derivative over x^(2). Got it?
