              Explanation (300 Words):<\/h3>\n\n\n\n

              Each expression is solved using PEMDAS\/BODMAS<\/strong> to ensure accuracy. Parentheses are resolved first to simplify groups of operations. Next, multiplication and division are handled from left to right. Finally, addition and subtraction are performed in sequence from left to right. This structured approach ensures that all steps are followed logically and nothing is skipped, especially when handling both positive and negative numbers or multiple operations in one expression. Calculations must strictly respect this hierarchy to avoid errors.<\/p>\n","protected":false},"excerpt":{"rendered":"
