Hello guys actually I was taking Arithmetic quizz 1, and I countered with a question below

3³ - 2 × 4² - 3 + 7 ÷ 7 and the answer for this question is 2, but when I applied PEMDAS rule here, I’m getting -7.

Then I checked the explanation video of this quizze, And I found lil bit different question, which includes parenthesis ()

3³ - 2 × (4² - 3) -7 ÷ 7.

So is this a same question, or its different…? And what’s the correct answer for this…?
