In real gases both the pressure and volume are lower than that of ideal gases. pressure is lower because force of attraction is not negligible. volume is lower because volume of gaseous molecules are not negligible. then why the correction term in volume case is subtracted ( in van der waals equation) and in pressur term is added?? both the correction terms " nb " and " an 2 /v 2 " should be subtracted. why it is not so? please explain.

b is the volume excluded by a mole of particles
