For example, to solve the expression 3 + 5 * 2 - 1:

  • Exponents are calculated next.
  • Although PEMDAS specifically addresses the simpler mathematical operations, variations of the concept cover more complex expressions and operations involving fractions and decimals, ensuring that mathematical expressions are evaluated in a methodical and standardized manner.

      • In recent years, the acronym PEMDAS – a seemingly simple concept that underlies a fundamental aspect of mathematics – has gained widespread attention online, particularly in the US. Once the subject of academic offices and hallways of learning, the Order of Operations is now part of a streaming media trend, sparking curiosity and debate among math enthusiasts and non-math enthusiasts alike. What's behind this sudden surge of interest? Before exploring its growing popularity, it's essential to unravel the mystery that lies at the heart of this often-misunderstood concept.
