So you wanna determine if you is in the north off, eh? So we check. So check if something is in a normal off A with check if a more supplied by your equal to zero now is given us in exercise aids. So it is minus three 06 minus two. So three zero minus 63 more to blood by minus 231 If you multiplied these, you're gonna get 000 So the answer is yes. A are you isn't a normal off, eh? So yes, you is being no off.
