What is the hardest subject in math?
I'm curious, what would you say is the most challenging subject in the vast realm of mathematics? Is it the intricate world of calculus, with its daunting derivatives and integrals that seem to defy comprehension? Or perhaps it's the abstract and often mysterious realm of number theory, where primes and proofs hide in plain sight? Or could it be something else entirely, a field that pushes the boundaries of our understanding and leaves even the most seasoned mathematicians scratching their heads? I'm eager to hear your thoughts on this perplexing question.
