Simplify the expression: 25 - (18 - 4 × 9 ÷ 3)

Question

Accepted Answer

Step 1: Evaluate the expression inside the parentheses: (18 - 4 × 9 ÷ 3)
Step 2: According to BODMAS, first do multiplication and division from left to right:
4 × 9 = 36
36 ÷ 3 = 12
Step 3: Now substitute back:
18 - 12 = 6
Step 4: Now the expression becomes:
25 - 6 = 19

Rechecking the options, 19 is option 4, but the initial marking was 31. Let's carefully re-evaluate.

Re-evaluation:
Expression: 25 - (18 - 4 × 9 ÷ 3)
Calculate inside parentheses:
4 × 9 = 36
36 ÷ 3 = 12
So inside parentheses: 18 - 12 = 6
Now 25 - 6 = 19

Therefore, the correct answer is 19 (option 4).
