Measuring the wavelength of light using diffraction

I did an experiment last week in my college physics class where we measured the wavelength of light using single, double, and multiple slit diffraction and diffraction grating. Using the measurements and Young's equation, we calculated the wavelength of the light. My teacher said that as we use more slits, we should get more accurate results. Can someone explain why this happens?
