/sci/ - Science & Math

I have a test tomorrow, and have a few questions.

>If I have a square root number thats negative, like -27, but I have a index of 3 (or odd number), is it still considered an imaginary number?

>if I have a fraction, and I only have the numerator or denominator with a negative number(-3/4), does the fraction stay negative? (like multiplying with a negative number)?

>this kind of same question is previous, If both numerator and denominator have a negative number does it go to positive? (-3/-4) -> (3/4)

>what method(s) do you have to understand, and label complex and other types of numbers? (real,imaginary,irrational,integer,non-integer,counting,real etc..)

Supposedly being alone is as bad as smoking a pack of cigarettes a day

>whine about having to go to crap uni
>whine about doing subject I hate, I'd rather be doing maths/physics/computer science
>have access to shitloads of online courses from top tier unis
>never bother to use any of it, just browse 4chan
>realise I am a supreme plebeian

Anyone else in the same boat?
