Suppose we have lots of forces F1,F2,F3 etc acting at a point. Then pressure would be the magnitude of vector sum divided by area , limit of area tending to zero or just sum of magnitude of individual forces divided by area, limit of area tending to zero.(adsbygoogle = window.adsbygoogle || []).push({});

Also if we are given a surface and pressure on it is P, then we say force on the surface is FA (but keep in mind my above doubt), what is the direction of this force?

Please tell me all the subtle points like these about pressure.
