In the context of mathematics, what distinguishes 'pure mathematics' from 'applied mathematics'?

  • There is no real difference; the terms are interchangeable.
  • Pure mathematics focuses on theoretical concepts, while applied mathematics uses these concepts in other disciplines. (correct)
  • Pure mathematics deals exclusively with integer numbers, while applied mathematics deals with real numbers.
  • Pure mathematics is more concerned with solving equations, while applied mathematics focuses on geometric proofs.
