Just want to get a straight answear if possible..(adsbygoogle = window.adsbygoogle || []).push({});

How dou you add different types of errors.

lets say I have and length error of 2 +-1 and another of 5+-2

what happens to the error when I add/subtract....multiply/divide...square/sqrt ?

then If I have and length error of 2+-1 and a mass error of 20+-1 and first I change the absolut error to percentage, and then what happens when I:

add/subtract....multiply/divide...square/sqrt ?

Doing lot's of labs and just need some clarification on this..

would be nice if someone could show how to with these examples... thanx alot guys & girls
