I'll be glad to check your answer.
Tom, unless you know how to do these, please refrain from giving incorrect answers.
3 -(-3)²-2
= 3 - 9 - 2
= -8
To calculate the expression 3 - (-3)² - 2, follow the order of operations (PEMDAS/BODMAS). Here's the step-by-step calculation:
1. Start with the parentheses: -3 squared.
-3² = (-3) * (-3) = 9
2. Replace the parentheses with the computed value: 3 - 9 - 2.
3. Next, perform the subtraction operation from left to right:
3 - 9 = -6
-6 - 2 = -8
Therefore, the final result is -8.
