5) \( (54-30): 4 \)

Did you know that the order of operations—often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction)—was standardized to help avoid confusion in complex equations? This helps ensure that everyone arrives at the same answer when solving mathematical expressions! When tackling problems like \( (54-30) : 4 \), it’s easy to forget to perform subtraction inside the parentheses first. So, first, subtract 30 from 54 to get 24, and then divide by 4 to get 6. Following these simple rules keeps your math in check and your answers accurate!
