So like. I haven't done math in a long time.
I want to learn some hard math.
Is there a website that will teach me hard math and then I can do tests for free? Thanks math men.
Ps I know a guy that has a degree in math. But he's a friends brother and moved.

Try edx or coursera or something like that. Type "free online classes" into a search engine.

No you Indian
If shit is positive then sqrt(-shit) = i sqrt(shit)
(i sqrt(shit))^2 = -shit

You're wrong. Absolute value is defined as (sqrt(x))^2.
