# What is the relevance of Maxwell's equation being linear?

My prof in my intro to electrodynamics class briefly mentioned that the linearity of Maxwell's equations is related to the superposition of electric fields by point charges, but I don't see how. Would someone please elaborate on this?

• The solution to the equations for the fields for $$N$$ point charges is just the sum of the solutions for the fields of the $$N$$ individual charges.
