Final answer:
The answer to the student's math problem "-81 divided by 3+6•-3" is -45, following the order of operations PEMDAS.
Step-by-step explanation:
The student is asking for help with a math problem involving the order of operations, also known as PEMDAS (parentheses, exponents, multiplication and division, and addition and subtraction). The specific math question is: What will be "-81 divided by 3+6•-3"? Let's solve this step by step:
- According to the order of operations, we first deal with division and multiplication before addition and subtraction.
- So, we divide -81 by 3 which equals -27.
- Then we calculate 6 multiplied by -3, which according to multiplication rules, results in -18 because the signs are opposite.
- Lastly, we add the results of the division (-27) to the multiplication (-18).
- -27 + (-18) = -27 - 18 = -45.
The correct answer is -45.
