The underlying ideas for even simple math are deep. Just because you get As doesn't mean that you grok concepts deeply. Examples: place notation, rational and irrational numbers, axiom, proof, correspondence, logic, countability, etc... The formulations of these ideas were intellectual breakthroughs thousands of years ago. It's takes curiosity to explore these more deeply.
