math.abs() will make any number positive.
Ahh yes, returns the absolute value of a number.. forgot about that but making it * -1 is easier xD

Yes, but the question is whether you want an absolute value, an inversion, or just to reassign the value of 10. And I personally can't really say which is being requested here.

Really, the best way of doing this is:
Now, if you are saying that you want this to ONLY change negative to positive, this might be good:
somevar = 65
somevar = somevar*-1
Now, if you are saying that you want this to ONLY change negative to positive, this might be good:
somevar = 65
if somevar < 0 then
somevar = somevar*-1
end

No. The best way to only change negative to positive is math.abs(). That's what it's there for, that's the whole point of it existing.
