PEMDAS will help you make sure you get the correct answer. If you don't use it then you'll get a completely different answer.

Use PEMDAS in this problem. First you would need to multiply the numerator before you can subtract.

Once you multiply you can subtract. Lastly you just need to divide to get your answer.

Also, 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.

\(\dfrac{10 - 2 \cdot 4}{2} = (10 - 2 \cdot 2) \div 2 =\) \(= (10 - 8) \div 2 = 2 \div 2 = 1\)
