/sqt/ Stupid Questions Thread: Oxford Capacity Analysis Edition

Why are some units wrote with a subtraction? Such as m^3 being m^-3.
I've done maths up to calc 2 and still don't know this.

>Such as m^3 being m^-3.
As in cubic meters, not an algebraic unknown.

1 m^-3 is the same as 1/m^3 and means "1 per meter cubed"

It could mean, say, you have 1 atom of uranium in every cubic meter of space.

Okay so, 2.5 x 10^25 molecules m^-3 is equivalent to saying 2.5 x 10^25 per m^3.

yes

What have you tried?

I'm a CS student, I've done some linear algebra, vector calculus, discrete math and probability at uni. I'm interested in more math disciplines, outside of CS focused of course, where should I look in terms of material/textbooks?

What is the common ratio for 1/n^2?
I can't understand how you can get a common ratio from when the n is squared.

1+1/2^2+1/3^2 etc
because it changes at all times.
