Yeah doesn't make much sense. But then again we did algebraic operations on letters in university some time ago. Not variables, actual letters. It was for programming sentence structures.

Huh, and how did that work?

There's a certain way you can write down exactly how the grammar for a programming language works. Or any grammar for that matter. I forgot how it was called.
Here's an example for a normal sentence.

N={Sentence, Subject, article, noun, verb, object}
T={the, mouse, likes, cheese, . }
P={Sentence= Subject + verb + object + ".";
Subject= article + noun;
article= "the";
noun= "mouse";
verb= "likes";
object= "cheese";}
S= Sentence;

N are certain structures of the thing, the words in "" are the outputs and S is with what the program starts. It starts with sentence and decodes it to Subject + verb + object, next the structure Subject gets decoded to article + noun and so on until you have your sentence "The mouse likes cheese."

You can make it recursive too.

N={A, B}
T={0, 1}
P={A= "0"+B;
B="1"+A;}
S=A;

This would lead to an infinite line of 0101010... and would be written as (01)^n where ^n is not to the nth power but 01 times n as in the string 01 is written n times.

So taking the n-th root of the long string would results in the base string?

Pretty much I guess. There's ways to make it finite length by using "or" operators, written as | . So for example
A= "1"+b
B= "0"+A | "0"

S=A

can be anything from a single 10 to infinite 101010... Single 10 would be (10)^1 , 1010 would be (10)^2 and so on. the term is still written as (10)^n with n being the amount of repetitions. And you can do that for pretty much anything you can write down.
They gave us a sheet with a simple grammar for java programming. Which was 1 full page. Then we got 2 program lines and were supposed to search for 4 small mistakes inside using the grammar. Which took another 2 pages of writing to find out that there was a ")" missing or that they wrote =< instead of <=

Math is the reason I never seriously considered pursuing the sciences.

Out of curiosity, how have you been thought it? "Memorise this and this formula and apply it exactly as told" or building it up from logic and emphasising on understanding and problem solving more.

Formulas everywhere. Especially when it came to that Physics class.

Yeah, math is pretty lame then. I think math can be very beautiful and amazing when you see how perfectly everything fits together.

However I could never get into pure math, too abstract and complex for me.

Math is fine, really the problems I've had with it are because we moved so quickly onto new concepts that I never properly learned the first concepts, so it took me a while to see how things fit together. When I didn't see how they fit, I had to resort to formulas everywhere.

Also I have trouble applying new concepts in a way that my brain can make sense of it. Not necessarily applying them to real-world problems, but it's like I have to rewire my brain to follow each different set of steps, I suppose. Though I think that's related to not having a strong foundation of prior concepts, like I said above.

Math is fine with me if there is something to apply it to. Geometry was easy for me, because these are shapes, and I can see how the equations fit into the shapes.

Algebra II is hard as shit, because it's just a lot of numbers so far. Also fractions. By god fractions. Why can't things just be fucking decimals.

Algebra in University: Numbers? What's that? We use the alphabet and greek alphabet for maths, what else should we use?

Because (according to my teacher) decimals are fugly and DUMBDUMBSTUPID and suck mad dick and fractions are much easier

Yeah fractions are really much cleaner than decimals as long as you don't get something absurd like 669/7 or some crazy shit.
It's because fractions are inherently less accurate, as many decimals would produce fractions that go on forever like pi or 1/3.

On the subject of which math we prefer, I'm really digging trigonometry so far.
All the formulas are pretty easy to figure out and make sense of, and the trigonometric functions all go together really nicely in most of them.

Also, is it just me, or is this article saying that some students revolutionized cooling by figuring out you can use a microwave instead of some hella expensive lab equipment?

That's a very crude way of putting it, but sort of yes.

Fractions are the least of my worries, I'm currently rustled off about something which I don't know the English word for. Uh, They have to do with Taylor and Maclaurin? With a summation sign and powers of x? You can use them to define transcendent functions and such.
