  1. Groups: Parentheses ()( ), Brackets [][ ], and curly braces {}\{ \}

  2. Exponents: Powers (x2x^2) and square roots (x\sqrt{x})

  3. Multiplication & Division: Evaluated from left to right in order of appearance

  4. Addition & Subtraction: Evaluated from left to right in order of appearance

Writing the acronym vertically helps prevent the common trap of prioritizing multiplication over division or addition over subtraction:

P (or B)E (or O/I)MD (Left to Right)AS (Left to Right)\begin{aligned} &\mathbf{P} \text{ (or } \mathbf{B}\text{)} \\ &\mathbf{E} \text{ (or } \mathbf{O} / \mathbf{I}\text{)} \\ &\mathbf{MD} \text{ (Left to Right)} \\ &\mathbf{AS} \text{ (Left to Right)} \end{aligned}

Sofia’s Clever Riddle

By phrasing her age as 6−1×5+8÷26 - 1 \times 5 + 8 \div 2, Sofia wasn't just giving a number—she was setting a clever literacy test in basic mathematics. While the equation looks like a confusing tangle of symbols designed to mislead casual readers, following standard mathematical grammar cuts straight through the noise.

Sofia is 5 years old, a preschooler who has already mastered the art of stumping grown adults across the internet.
