for # 2 - what about the order of operations? PEMDAS. Parentheses, exponents, multiply, divide, add, subtract??

I double checked all the answers and you did great. 1,3, and 4 are exactly correct!! Good Job! Number 2 is wrong. I got 0 for number 2 because 6(4)-2(3)(4) = 24-24 = 0.
Hope this helps.

I got different answers for 2 and 3. I believe you've got them wrong. Remember order of operations. In 2 do all multiplying first.
In 3 do parentheses multiplying then subtraction, in brackets multiplying then addition, and finally multiply the outside number.

1., 3. and 4. are correct.
Did you copy problem 2. correctly? If so, then the answer is wrong.
