The problem comes with whether you divide 6 by 2 first or multiply 2 by what's in the parentheses first. It's weird because, at least in my experience, you don't use the division symbol very often, you just use fractions for division which have implied parentheses around the numerator and denominator. As it's written in the picture, the answer is 9, but if you replaced the division symbol with a fraction, the answer would be 1.
