What means to perform all the indicated operations to an expression in math?

To perform all the indicated operations on a mathematical expression means to follow the prescribed sequence of calculations, typically adhering to the order of operations. This order is often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). Each operation should be executed as specified, ensuring accuracy in the final result. Ultimately, this process simplifies or evaluates the expression correctly.
