" simpler" is an adjective that describes something as being easier or less complicated, while "more simply" is an adverbial phrase used to express the manner in which something is done. For example, you might say, "This solution is simpler than the previous one," to highlight that the solution has fewer complexities. In contrast, you could say, "We can explain it more simply," indicating the intention to present the information in a clearer or easier-to-understand way.
