Determining the "most difficult sum in the world" is subjective and depends on various factors, including mathematical context and individual expertise. However, problems like the Riemann Hypothesis or certain unsolved equations in number theory are often cited as extremely challenging. These problems remain unresolved and pose significant challenges for mathematicians, making them candidates for the title of difficult sums. Ultimately, the difficulty of a sum also varies based on the solver's knowledge and experience.
