are u sure
I apologize for the incorrect answer. Let's evaluate the expression step by step:
3 + 6 × (5 + 4) ÷ 3 − 7
Step 1: Parentheses
(5 + 4) = 9
3 + 6 × 9 ÷ 3 − 7
Step 2: Multiplication
6 × 9 = 54
3 + 54 ÷ 3 − 7
Step 3: Division
54 ÷ 3 = 18
3 + 18 − 7
Step 4: Addition
3 + 18 = 21
21 − 7
Step 5: Subtraction
21 − 7 = 14
Therefore, the value of the expression is 14.
Correct answers:
Question 1: D) Perform any calculations inside parentheses.
Question 2: C) 14
