Can you guess this science riddle?

Well, mathematically speaking you cannot subtract the extra “m” out of the mass of the density, you only can take out a m/V, so you can take the density of the rock off the boat but not the actual mass. So, the density goes off the boat but the mass stays which means the inner frequency dynamic of the rock stops inside on the boat and the density(which represents the collision of the photon inside of the particles of the rock) goes off the boat adding to the water which means the water density increases and so the water levels drop, that’s if you are a being prime and you value mathematics(number 5) more than physics(number 3).
