That means for ideal pressures, ideal pressures are higher than real pressures. Likewise, let's examine the conditions for volume of ideal versus volume of real. Now, the volume of ideal is less than volume of real because when you're taken into consideration the volume of real gases you're taking into consideration the volume of the molecules. And that means the volume will be plus the volume of the molecules. And so the volume of real gases will be greater. So now let's see what the gas law is for real gases.
