The acronym commonly used to remember the order of operations in math is PEMDAS. It stands for:
- Parentheses
- Exponents
- Multiplication
- Division
- Addition
- Subtraction
A popular phrase to remember this acronym is "Please Excuse My Dear Aunt Sally."
In some contexts, you may also come across the acronym BIDMAS (Brackets, Indices, Division, Multiplication, Addition, Subtraction) or BODMAS, especially in regions like the UK. Each of these acronyms represents the same order of operations but uses slightly different terminology.
