Final answer:
The expression 3 + 5 × 5 - 9 ÷ 3 × 4 equals 16.
Step-by-step explanation:
The expression 3 + 5 × 5 - 9 ÷ 3 × 4 can be solved using the order of operations. First, we perform any multiplication or division from left to right. So, 5 × 5 equals 25 and 9 ÷ 3 equals 3. Now the expression becomes 3 + 25 - 3 × 4. Next, we perform any addition or subtraction from left to right. So, 3 + 25 equals 28 and 28 - 3 × 4 equals 28 - 12. Finally, we perform the remaining subtraction, 28 - 12, which equals 16.
