Uncertainties/error propogation

  • #1
i know the following:

q = x+y+z

ERROR IN q = sqrt((error in x^2)+(error in y^2)+(error in z^2))

but, what if the equation i have is

q = x+y-z

would it still be that same equation or would it be,


ERROR IN q = sqrt((error in x^2)+(error in y^2)-(error in z^2))

It would be the same equation, add the error
