/sci/ - Science & Math

You can't learn finance formulas because they're stupid and boring, and don't make any sense. Unless you're a soulless roboto. Physics and maths formulas are cool and beautiful so they easily stick in your brain. Thanks for listening.

We trust that notation was invented by geniuses that were thinking about how the shape of a formula would reinforce its meaning and vice-versa, creating an infinite feedback loop in your brain that would allow for easy memorization. It works, as I don't need to store entire formulas in my brain but just their shapes, and then the details slowly come to me as I start writing it. The best example is, in my opinion, Stokes' Theorem.

I don't know about finance but if you have a lot of boring formulas written by uninspired hacks then odds are you do have to store the entire content in your brain, which would be a hassle.

>>9938350
this, but unironically

>>9938350
by this logic, shouldn't some engineering formulas be hard to memorize as well? Quite a lot of them tend to be more empirical and make no sense when it comes to the dimensions

>>9938335
Don't learn formulas, learn their derivations. You don't understand something if you can't justify it.

>>9938403
Some engineering formulas, but most of the ones you learn in undergrad are pretty simple. If you can't remember it exactly but the units work out, chances are it's right.

>>9938335
What are some finance formulas?

>>9938424

>learn the derivations

There are hundreds of derivations...how do you remember all of them?

>>9938350
genius is a meme

>>9938335
hardcore maths has basically no formulas

>>9938446
Future value of money = PV(1+i)^n

>>9938498
What is this shit?

Finance formulas are easy as shit just go be an excel bound brainlet for the rest of your life

>>9938541
PV = Present Value
i = Interest Rate
n = Number of Periods

>>9938447
work through them. If you're not a brainlet, and at least know where to start and know a few bits and pieces from the derivation, you can fill in the gaps that you forget.

>>9938560
Then that formula is obvious

>>9938563
All formulas are obvious

Just change your A to an E and you're on your way to finding the solution

>>9938560
In that case, it really is a trivial formula.
You can derive it just knowing basic algebra.
If it doesn't seem obvious, you should think about it until it does.

>>9938335
Drawing, creating stories around it, relating it to phrases or things that are not that common to think about, etc.

Also, just put a bunch of papers with formulas thru your house or even as your pc/cp background. It will easily stick to your mind after some time.

The biggest problem I have with finance formulas are that it doesn't seem like order of operations exist. For example here, I thought I had to multiply 20% by (30/30+10) but what I actually had to do was multiple 30% by 30 THEN divide that by 30+10

>>9940152
20%*

>>9940152
this has to be trolling

>>9940156
I don't know, the average /sci/ IQ has been pretty low lately.

>>9940156
Why?

>>9940161
Because the order of operations doesn't fucking matter here.
60/40 = 20*30/40

>>9940162
0.2 *(30/30+10) = 2.2
(0.2 * 30)/(30+10) = 0.15

>>9940166
Go fuck yourself.

>>9940167
Why are you being so mean?

>>9940169
You are trolling or an exceptionally dumb person badly pretending to be smart, either way you don't deserve respect.

>>9940166
are you in biz school right now OP?

If you're actually in college I would seriously recommend getting remedial math help.

>>9940172
>>9940173
I don't get it; what's wrong?

>>9940177
See the red line?
The red line means you divide the stuff on the top by the stuff on the bottom.

The stuff on the top is 30
The stuff on the bottom is 30+10

0.2*(30/30+10) is fucking wrong.

Literally basic shit we all should have learned in 6th or 7th grade even before pemdas.

>>9940187
But how do you know you divide 30 after multiplying it by 20%?

>>9940194
Once you add 30 and 10 the order of the other stuff doesn't matter.

>>9940166

Sorry not everyone is a genius

>>9940205
I guess the only way to have an average when there are people above average is to have people below average. Enjoy being the other side of the seesaw man.

>>9940166
Pic related is for you

>>9941626
now that's a first, no idea why it went upside down, but still there you go i guess

>>9941628
Pictures taken by phones or some modern digital cameras are usually rotated using exif data because the computational load of pixel rotation makes it hard to do while taking the picture.

This exif data is stripped when uploaded to 4chan (to keep people from doxxing themselves) so the picture appears in the orientation of the phone/camera sensor.

Top kek my dude your degree is shit hope you at least have good connections

>>9942016
i didn't know that, thanks anon.

>>9942093
literal brainlet

>>9938335
Only brainlets learn formulas
Real math involves learning proofs

Use formula cheatsheets, there is literally no reason to attend college to learn any of this. Just follow directions.

>>9943060
Just look behind the formula.

>>9938424
>learn their derivations
how does one go about this :thinking:
t. brainlet
