I respectfully disagree. A graphing calculator is permitted so if student types 14 into the calculator the last thing done is divide. So, in my opinion number 14 has 3 correct answers, not one or two. I thought one goal was to strive for higher order thinking skills and to give credit for different ways to do a math problem. This causes me much distress when the rubrics for parts II,III and IV do not address all ways a student may do a problem. A zero response is completely incoherent etc and some students did some mathmatics that if no mistakes were subsequently made would have arrived at a correct solution. Did Albert Einstein think inside the box or outside? I apologize for my ramblings.
