Which math is hardest?

So, the question we're asking today is: "Which math is hardest?" It's a common inquiry among students and educators alike, as mathematics is a vast and complex field with many different branches and disciplines. Some might argue that calculus is the most challenging, with its intricate concepts of limits, derivatives, and integrals. Others might point to abstract algebra, which deals with abstract structures and properties, often far removed from the real world. And still others might contend that number theory, with its focus on the properties of numbers and their relationships, is the toughest nut to crack. But ultimately, the answer may depend on individual interests, strengths, and weaknesses. So, which math do you find the most daunting? Let's delve into the debate and explore the various perspectives.
