Problem in most cases, refers to an issue requiring or asking for a solution.

Problem can refer to:

• in mathematics, a problem is a question about mathematical objects and structures requiring explanation and proof. These questions range from very specific ("What are the real solutions of x² + 1 = 0?") to quite general ("Why do these numbers appear in apparently different situations? Formulate and prove a conjecture.")
• in society - a problem can refer to particular social issues, which if solved would yield social benefits, such as increased harmony or productivity, and conversely diminished hostility and disruption.
