I did not read any posts, but i would have say the answer is 2. Woking inside the lil bracket things first 9 plus 3=12. The multiply 12 x 2 (which is the number outside of the lil braket things) equals 24. so, 48 divided by 24 = 2. I am probably wrong, since there is probably some rule in math like the I before E except after C thing,but I really just wanted to say "lil bracket things" instead of wasting time typing parenthesis
