So we need to figure out something? XD

[The Abacus]

I never knew it was a puzzle either XD

[Vortex]

Google says it's the amelia sequence, that was invented for a show or something.

EDIT: and it draws some relations, but I don't know if they're significant at all...

Okay, so how do you solve shit like
(x^2)-x=870
Like, I know it's 30 know, but how do you solve it
it's been driving me mad ahhh
(^ means a power)

[Anteroinen]

Well,

x=(-b+/-sqrt(b^2-4ac))/2a

I think.

[Vortex]

Yeah, you have to put it in the form a*x^2 + b*x + c = 0 (in your example it would be 1*x^2 -1*x -870 = 0), and then use the formula Anteroinen told above (there are always 2 solutions).

In your example:

x1= (1 + sqrt((-1)^2-4*1*(-870))/2*1 = (1 + sqrt(3481))/2 = (1+59)/2 = 60/2 = 30

and the other solution:

x2= (1 - sqrt((-1)^2-4*1*(-870))/2*1 = (1 - sqrt(3481))/2 = (1-59)/2 = -58/2 = -29

Over thinking it.
It is related to a show, but I made the connection in real life.

[Boingo]

Phi. 1.618.
Awesome number.

[The Kakama]

Indeed, you could do all sorts of fun stuff with it.

[Boingo]

I could measure the dimensions of my head, for example.
