Hi Hans,

Yes this is the case in recent versions of mkiv, but in Plain TeX and mkii this is not the case: there the minus sign in \pm is aligned with the baseline.

I agree with Sanjoy and Mikael to say that it the minus sign in \pm should be aligned with the baseline: however I don’t know if this can be easily achieved.

Best regards: OK
