Final answer:
To evaluate the postfix expression '532* + 4 - 5 +', follow the order of operands and operators, resulting in a final value of 12. So the correct answer is option D.
Step-by-step explanation:
The question asks for the value of the given postfix expression: 532* + 4 - 5 +. To evaluate a postfix expression (also known as Reverse Polish notation), one must follow the operands and operators in their order, performing the operations as they appear, using a stack to store intermediate results.
After performing all operations, the final result on the stack is 12. Therefore, the given postfix expression evaluates to 12. A mathematical notation in which operators come after their operands is called a postfix expression, sometimes referred to as a postfix notation or reverse Polish notation (RPN).
Because the operators' positions define the sequence of operations, the mathematical expressions in this notation can indicate the order of operations without the need for parenthesis.
