Best ResponseYou've already chosen the best response.0PEMDAS will help you make sure you get the correct answer. If you don't use it then you'll get a completely different answer.

Best ResponseYou've already chosen the best response.2Also, a fraction means division and parentheses. \(\dfrac{10  2 \cdot 4}{2} = (10  2 \cdot 2) \div 2\) Notice how the numerator of the fraction is all grouped in parentheses. This is what I meant before when I wrote that a fraction also means parentheses in addition to division.
