Final answer:
The expressions (a + b) / c and a + b / c will not always yield identical results.
Step-by-step explanation:
The expressions (a + b) / c and a + b / c will not always yield identical results. The order of operations, also known as the PEMDAS rule, states that multiplication and division should be performed before addition and subtraction. In the expression (a + b) / c, the addition is performed first and then the result is divided by c. However, in the expression a + b / c, the division is performed first and then the result is added to a. This leads to different outcomes in most cases.
