What is the last operation to perform according to PEMDAS?

• A. Subtraction
• B. Multiplication
• C. Addition
• D. Exponentiation

Answer: (C)

In the order of operations known as PEMDAS, which stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right), the last operations to be performed are Addition and Subtraction. These operations are grouped together because they are of the same rank in the hierarchy of operations. When evaluating expressions according to PEMDAS, you start with any calculations inside parentheses, then handle exponents, followed by multiplication and division, and finally, you perform addition and subtraction. Since addition is one of the last steps, it is essential to remember that it comes after all preceding operations have been completed. It's important to note that both addition and subtraction are treated with equal priority and are performed from left to right, meaning you will resolve them in the order they appear. Thus, choosing addition as the final operation is consistent with the rules of PEMDAS.
